House Flip Financing: How to Structure 100% Funding for Your Flip

For most new real estate investors, funding is the single largest barrier to getting a deal done. The purchase price typically requires a 20% to 25% down payment from the investor's own pocket.

Most hard money lenders and fix and flip lenders will not truly finance 100% of a deal. They cover a portion of the purchase, fund rehab draws, and leave the investor responsible for the down payment, closing costs, carrying costs, and contingency reserves. That leftover amount kills deals for investors who have deal flow but not deep cash reserves.

The way around it is to combine a primary fix and flip loan with a gap funding layer so the full project cost is covered. Here is the basic structure:

Primary loan (hard money or private lender) covers most of purchase and 100% of rehab draws.
Gap funding (unsecured term loans, 0% business credit cards, HELOC, business lines of credit) covers down payment, closing costs, reserves, and cash flow gaps.
Combined, the investor brings little to no cash to closing.

Below is how each piece works, what it costs, and where the risks are.

Fix and Flip Financing Basics

Fix and flip financing refers to short-term, business-purpose loans designed to help real estate investors buy, renovate, and resell investment property for profit. These loans focus on the property's potential value after renovation, not on whether the borrower plans to live there.

Key terms used throughout this post:

Purchase price: what you pay the seller at acquisition.
Rehab budget / renovation costs: total estimated cost to renovate.
ARV (After Repair Value): the projected property value once rehab is finished, validated against comparable sales.
Loan-to-cost (LTC): loan amount divided by total project cost (purchase + rehab).
Loan-to-value (LTV): loan amount divided by ARV.
Term length: typically 6 to 18 months. Fix and flip loans typically have a 12-month term.

Monthly payments on most flip loans are interest-only; principal is due when the property sells. Some private money lenders offer deferred interest or pay-at-exit structures, meaning no monthly payments during the project.

True costs associated with a flip include holding costs, selling costs, and financing fees. Selling costs typically include a 6% commission on the sale price, which many first time flippers forget to model.

Conventional mortgage vs. fix and flip loan

Interest rate: Conventional 6% to 8% | Fix and flip 9% to 15%
Underwriting focus: Conventional: borrower income, credit | Fix and flip: property value, ARV, deal quality
Term: Conventional 15 to 30 years | Fix and flip 6 to 18 months
Rehab funding: Conventional: none | Fix and flip: yes, via draws
Closing speed: Conventional 30 to 60 days | Fix and flip 5 to 14 days
Down payment: Conventional 20% to 25% | Fix and flip 10% to 25%

That speed gap matters when competing for distressed properties.

Types of House Flip Loans Investors Actually Use

There is no single "best" flip loan. The right option depends on time-sensitivity, credit profile, track record, and project risk.

Hard money loans. Close in 5 to 14 days. Hard money loans can provide up to 90% financing for purchases plus 100% of rehab draws. Best for distressed properties where speed wins the deal.

Private lenders. Individuals who provide funding based on personal relationships or direct negotiations. Rates often land at 8% to 10% with fewer points. Useful when you have real estate expertise and a relationship with the lender.

Bridge loans. Short-term financing for quick property purchases, often used when an investor needs to close before selling another asset. Terms overlap with hard money but may offer lower rates for clean deals.

HELOCs / home equity loans. Allow borrowing against home equity as needed. Lower cost than hard money but limited to available equity in a primary residence or other owned property.

Personal loans. Can offer up to $100,000 for borrowers with good credit. Useful for filling small gaps like closing costs or contractor deposits.

Business lines of credit. A revolving line of credit secured by business assets or revenue. Good for covering materials and short-term cash flow gaps.

Seller financing. The seller carries part of the purchase price as a second lien, which can reduce the investor's upfront capital requirement.

Hard Money Loans: The Backbone of Most Flip Projects

Hard money lenders specialize in asset-based, short term loan products where the property and its ARV matter more than traditional income verification. The borrower's experience helps with rate and leverage, but the collateral drives the approval.

Typical hard money loan terms:

Interest rates: 9% to 15%
Origination fees: 1 to 3 points (1% to 3% of loan amount)
Term: 6 to 12 months, sometimes 18 for larger rehab projects
Leverage: 85% to 90% of purchase and 100% of approved rehab budget
Monthly payments: interest-only
Approval focus: property address, purchase price, renovation scope, ARV comps, investor experience, exit strategy

Worked example: Atlanta flip

Purchase price: $240,000. Rehab budget: $60,000. ARV: $380,000. Hard money lender offers 90% of purchase ($216,000) and 100% of rehab ($60,000). Total loan: $276,000.

The investor still needs $24,000 for the down payment. Add closing costs (~$5,000), six months of carrying costs (taxes, insurance, utilities), and a rehab contingency buffer. That gap can reach $35,000 to $45,000.

Hard money alone rarely covers everything.

Other Financing Tools That Support Fix and Flip Projects

These tools work as either standalone financing on smaller deals or as gap funding layered on top of a primary flip loan:

HELOCs: Lower interest rates than hard money loans. A home equity line lets you draw funds as needed during a project. Home equity loans typically require at least 15% to 20% equity in a primary residence.
Home equity loan: Fixed-rate, lump-sum disbursement. Good for a known down payment amount. Secured by your home, so the collateral risk sits on your primary residence.
Business credit cards at 0% intro APR: No interest for 12 to 21 months on purchases. Useful for materials, contractor deposits, and smoothing cash flow between draws.
Unsecured personal loan: No collateral required. Typically needs 650+ credit. Monthly payments are amortizing, so model those into your carrying costs.
Business line of credit: A revolving line that recharges as you pay it down. Requires business revenue history (usually 2+ years and $20k/month revenue for traditional business funding).
Cash-out refinance: Requires at least 6 months of ownership, so this is an exit tool for BRRRR strategies, not a purchase tool.
Cash: Avoids interest charges and lender fees entirely. If you have liquid reserves, deploying cash for the gap portion while using hard money for the bulk keeps total cost low.

Quick example: An investor owns a home with $120,000 in equity. She taps a $75,000 HELOC for the down payment and uses a hard money fix and flip loan for the purchase and rehab. Combined, she brings zero cash to the closing table. Her monthly payments include interest-only on the hard money plus minimum payments on the HELOC.

Key Loan Terms Every House Flipper Must Understand

Small differences in loan terms change total financing cost by thousands of dollars.

Interest rate: The annual percentage charged on the outstanding loan amount.
Points (origination fees): Each point equals 1% of the loan amount, paid at closing. Two points on a $300,000 loan costs $6,000.
Loan-to-cost (LTC): Higher LTC means less cash from you; it also means more interest expense.
Loan-to-value (LTV): Usually capped at 70% to 75% of ARV by most fix and flip lenders.
Term length: Extensions typically cost 0.5 to 1 point per month.
Draw process: Rehab funds are released in stages as work is inspected. Expect to front costs between draws.
Prepayment penalties: Many hard money lenders waive them on fix and flip loans; confirm before signing.
Escrow fees: Title, insurance, and escrow fees at closing add 1% to 3% of purchase price.

Cost comparison: A $300,000 loan at 10% interest and 2 points over 10 months costs $25,000 in interest plus $6,000 in points, totaling $31,000. The same loan at 13% and 4 points costs $32,500 in interest plus $12,000 in points, totaling $44,500. That $13,500 difference is pure profit lost.

Experienced investors often compare lenders on rate, points, LTC, draw speed, and extension policies before locking a term sheet. The trade-off: higher leverage costs more in rate and points, but it lets you run multiple projects simultaneously instead of tying up all your cash in one deal.

How 100% House Flip Financing Actually Works in Practice

100% financing does not mean one lender writes a check for every dollar. It means your full capital stack covers purchase, rehab, carrying costs, and closing costs so you bring minimal or no cash.

Before you stack anything, run the 70% rule. It estimates maximum purchase price using ARV: you should pay no more than 70% of ARV minus renovation costs. On a $430,000 ARV property with $70,000 in rehab, that cap is $231,000. Arbitrarily estimating ARV without comps can lead to financial trouble, especially for first time flippers.

Higher leverage amplifies both profits and losses. Stress-test every deal by modeling ARV 10% to 15% lower than projected and holding time 3 months longer than planned. If the deal still works under those conditions, the capital stack is sound.

Step-by-Step: Building a Full Capital Stack for a Flip

Analyze the deal and confirm ARV and rehab budget. Pull comps, get contractor bids, and validate the renovation budget.
Get a term sheet from a fix and flip lender. Submit the deal to one or more hard money lenders or private lenders. Compare loan options on rate, points, LTC, and draw process.
Identify the cash gap. Subtract the primary loan amount from total cost. The remainder is your down payment, closing costs, rehab reserves, and monthly payments during the hold.
Line up gap funding. Share your deal details, credit profile, and the primary lender's term sheet with your gap funding source.
Lock primary loan terms and gap funding at the same time. Coordinate closing dates so both funding sources are ready simultaneously.
Close on the property, execute renovation, and manage draws. Fund materials and contractor deposits from your gap capital while draws from the hard money lender reimburse staged work.
Sell or refinance and pay off all short term loans. At resale, proceeds pay off the hard money loan first, then gap funding, then any remaining credit lines.

Timeline example: Investor goes under contract March 1. Primary loan and gap funding approved by March 15. Closing March 25. Rehab runs April through August 30. Property listed September 1, sold and closed by October 15. Total hold: ~7 months.

Underwriting: What Lenders Really Look For

While some fix and flip lenders market "no-doc" or "low-doc" programs, every lender still verifies investor capability through some combination of credit, liquidity, and deal quality.

Hard money underwriting (asset-based):

Property address, condition, and location
Purchase contract and purchase price
Rehab scope of work and renovation potential
ARV supported by comps (not arbitrary estimates)
Investor experience and track record (number of completed flip projects in last 24 months)
Exit strategy (sale timeline or refinance plan)
Credit score checked but not the primary driver

Gap funding underwriting (credit-based):

FICO score (650+ for most loan products)
Personal income or business revenue verification
Current debt obligations and liquid reserves
Home equity position if using HELOC products

Hard money lenders may not require full tax returns. Unsecured term loans usually require proof of income. Income verification requirements vary by product and amount.

Managing Monthly Payments, Draws, and Cash Flow During a Flip

Cash flow management separates profitable flips from break-even headaches.

Monthly payments breakdown on a $350,000 capital stack:

Hard money interest-only ($320,000 at 11%): ~$2,933/month
Gap funding term loan ($30,000 amortizing over 36 months at 12%): ~$997/month
Property taxes: ~$250/month (varies by county)
Insurance: ~$150/month
Utilities: ~$100/month
HOA fees (if applicable): varies

Typical carrying costs on this stack run $4,400 to $4,800 per month. Over a 9-month hold, that totals $39,600 to $43,200.

The draw process works in stages: complete a phase of work, request an inspection, receive funds 3 to 10 business days later. You must front costs between draws. Working capital or 0% business credit cards can cover materials and contractor deposits during those gaps and help prevent project delays.

Renovation costs can exceed initial estimates by 20%. Budget for this from day one, not after it happens.

Risks and Smart Guidelines for 100% Financing

Highly leveraged fix and flip financing carries real risk.

Key risks:

ARV comes in lower than projected due to market softening or bad comps
Renovation budget overruns (20%+ is common)
Longer days on market extend holding period and carrying costs
Contractor delays, permitting issues, or weather problems

Rules of thumb:

Stress-test every deal at 10% to 15% lower ARV than your best estimate
Add 20% contingency to every renovation budget
Model a 3-month longer hold than planned
Maintain reserves equal to 25% to 30% of renovation costs
Do not max out LTC if you lack experience; repeat borrowers earn higher leverage over time through a proven track record
Avoid running too many simultaneous flip projects until profits from completed deals provide a cash buffer
Model the 6% selling commission and your tax exposure into every exit projection

Final Thoughts

100% house flip financing is not a gimmick. It is a capital stack built from complementary lending products: a primary hard money or fix and flip loan for the bulk of the deal, and gap funding tools for the rest. At Gap Funded, this gap layer is what we work on with investors every day, and the deals that hold up are the ones with conservative numbers and a margin of safety built in.

For those of you flipping right now: how are you covering the gap between what your hard money lender funds and what the deal actually costs? Cash reserves, HELOC, credit cards, private money, or something else?
