Great advice and it fits our model down here in North Alabama. I have my own construction crew but its almost word for word what we do. We even backed off of the finishes on our flip properties because we were spending an additional 5-10% on things that "sold better" we found that pricing accordingly led to similar sales and cut down on the last 5% which is usually the most costly. White box paint, contractor grade finishes. Good home at a good price . Thank you for contributing to the community !

@BJ Everson I’d add change control as a sixth rule. The line-item scope works until a hidden condition appears or someone says, “while you’re there.” Before approving a change, I want the added cost, schedule impact and the original scope item it replaces documented. Otherwise the contingency quietly becomes a second budget and nobody can explain where it went. In older Rochester housing stock, surprises are expected; undocumented decisions are the part that usually makes them expensive.
@BJ Everson Great framework—especially scoping before pricing and tying draws to completed milestones. Hidden water damage would be high on my list of costly surprises: what looks like a small leak can turn into repairs to framing, subfloors, and plumbing once things are opened up.
I’d add one guardrail: document and price every change order before approving the extra work. A contingency helps absorb surprises, but it shouldn’t become permission for the scope to drift.
@BJ Everson Great list, BJ, and nice to meet someone working in Columbus! That's where we plan to start in the US.
Our costliest surprise was in Switzerland: a burst pipe flooded a ceiling, and we ended up repainting the whole floor at our own cost. Since then we price the "what if" scenarios before the job starts: as is, if the pipes need replacing, if the wiring does too. The owner sees every number upfront, and no stage gets paid until it's checked with photos.
Rule 3 is my favorite too. A draw tied to a finished, photographed milestone keeps everyone honest.
Since you know the housing stock there: if you had to price one "what if" upfront on a typical Columbus rental, which would it be: cast iron drains, old wiring, or the foundation?
Covering the “what ifs” is a must. And I point my clients to value add properties so we’re doing some of the needed work ourselves and know it’s done right before putting a tenant in place. That takes a lot of the “what ifs” off the table. But do like a contingency account in place for my client so they are covered for something happening , esp if they use the cash flow for their everyday uses.
BJ, rule 3 is the one I'd push hardest. Over 20 years of renovations and turns, the money I've seen leak wasn't from bad bids, it was from paying a draw on "done" that nobody actually walked. Mark's change control point fits right in: each change order should carry its own dated photo of the condition before and after, tied to the scope line it changed. Then the contingency has a paper trail. I built Eyes On the House™ (patent pending) to lock those photos to each draw. Happy to compare notes on what you check before releasing a draw.
@BJ Everson, thank you, and I'd really like to take you up on comparing notes!
Doing the needed work yourselves before a tenant moves in makes a lot of sense: you know what's behind the walls before day one. And a contingency account for clients who live on the cash flow is a smart detail.
One thing I'm curious about in Columbus: which exterior and roof work do you try to finish before the first freeze, and what waits until spring?
I'll send you a connection request here so we can stay in touch. Have a great week!
BJ this is solid. I'm in Delray 33446 Monarch Lakes - townhouse rehabs $60k range. Rule 1 and 2 saved me - scope before price and rental grade not retail. I was pricing retail LVP and $400 faucets and it killed my $242k to $420k ARV math. Now mid-grade, same rent $2100 low end comps. Rule 4 is real too - 10% contingency always goes.
Great breakdown, BJ! Point 3 and 4 are absolute lifesavers for keeping rehabs on track. As someone handling remote support, seeing how smart investors protect their margins is fascinating. Thanks for sharing these insights.
From a lender perspective, I'd add a 6th rule: validate your exit before you swing the first hammer.
I've seen plenty of rehabs go over budget because investors focused on construction costs but didn't verify rents, ARV, or refinance requirements upfront.
As for the costliest surprise, it's usually not the cosmetic stuff. It's the hidden items:
Foundation issues
Sewer line replacements
Knob-and-tube or unsafe electrical discovered mid-project
Structural damage hidden behind walls
Water damage that's spread further than expected
The common theme is that they're expensive, unavoidable, and rarely improve the property's perceived value dollar-for-dollar.
That's why I like your contingency rule. On older properties, a 10-15% reserve isn't a luxury, it's part of the budget. The investors who stay profitable aren't the ones who avoid surprises. They're the ones who plan for them before they happen.
Great comment! I always have 2 exit strategies before offering. Had a flip I was doing and everything that could go wrong went wrong in rehab so the margin wasn't there for the sale. But penned as a good rental so we just pivoted and didn't lose money.
BJ, taking you up on that. I spent 20 years running institutional SFR rehab, 300-plus homes a year, and your rule 3 is where most of the money goes. Paying on done when nobody walked it.
I've got a way to verify the walk without the drive and I'd rather hear how you handle it than pitch you. On a rehab two hours out, who actually walks it before you release a draw, and what makes you trust them?
