The architect presents a rough design that you approve after feedback from the builder and your sales expert. Once the architectural designs are complete we send it to the engineer so they can create a foundation and framing design. These are both required to submit for your permit (in Austin TX at least)
To prepare for doing the foundation, all of the following need to be considered.
1. Grade the lot - A flat lot is a good lot. Having a slope introduces lots of risk, all manageable though. You may have to step the foundation and create retaining walls. Make sure you have a plan for drainage to get rain water to the storm drains. You may need mira drains around the foundation. In the case of this project we did not need any of those. The lot was flat, so drainage wasn't much of an issue.
2. Remove any previous structures, foundations, removable trees and driveways.
This lot had an old tool shed with no utilities and a very old driveway. Driveways are usually concrete and cost just as much or more to dispose of the old concrete as to actually bust it up. Knocking down the shed was a simple task with the same back-hoe that pulled up the concrete.
If you have an existing structure, make sure you disconnect the services and have the utility pull the lines back away from the house. Even if you disconnect the service, if the lines aren't pulled back they can still cause a gas leak or electrical line discharge.
BUDGET
Time spent preparing your budget is time well spent. You make all of your money on the spread, and the budget is that plan. Work here will save you time and money which means it will increase your IRR. After you have done a few, they will take less work, but at first spend a good amount of time preparing and understanding your budget. You can use $/sqft generalities, but every project will have places that will cost more and less. Areas that cause price swings tend to be:
1. Foundation design - soils, slope, flood status and trees all influence this. Flat dry lots are the least expensive. Drainage and extra concrete to deal with a slope add cost.
2. Framing - This is generally an easy one to be consistent on. Exterior siding, special windows and roof types can be big cost influencers.
3. Mechanicals - The core set of AC, Electrical, and plumbing are pretty easy to predict. Big cost movers are fixtures, number of bathrooms, and number of can lights. HVAC is usually related strictly to size. If you have a two story unit you can spend more on a two zone HVAC system.
4. Insulation/Sheetrock - These are pretty standard rates and shouldn't fluctuate much. They are based on size of the house. Spray foam insulation costs a little bit more but is far more efficient. We us it in most of our homes.
5. Interior Finishes - The sky is the limit here. This is where you price out your home based on the area. You can make nice looking inexpensive homes with builder grade carpet, flooring, and countertops. You can also cut into your margins by buying things you think are nice, but you don't need for the market you are selling in. Don't price yourself out of the market or build the nicest house in the neighborhood.
6. Fencing and Decks - These can get expensive depending on how high you make them and what material you use. Stained treated pine looks great and costs less than cedar. Vertical fences are fine in most places, but horizontal ones look really sharp but are more expensive. They do have a big curb appeal though.
7. Landscaping - This is usually pretty fixed. However in hot climates like Texas I would recommend going with what they call xeri-scaping or no-scape designs that are mostly rock and cactus. Once you put that grass down, it starts dying. It's very hard to keep alive while you are showing your new home. It has to be cut and becomes a maintenance headache. A nice pretty rock garden it maintenance free. Be careful about your market here. This doesn't work everywhere.
8. Contingency - Plan for 5% to 10% of your budget in contingency for surprises. Worst case you will have a little left over. More likely there will be some surprise that this will cover.
I know you're probably thinking, what does each area cost? Well the prices I have are just for my area, so they are not reliable for all markets. I can't link a budget in the post, so you'll have to ask me directly and I'll send you my budget.
For each line item, use a cost code as well so you can track how much you are spending from project to project and make the book keeper's life a little easier.
BANK
If you are using a construction lender which is likely, make sure you get permission from the bank that it is ok to do grading and demolition before the loan is originated. Most banks will allow this assuming you can provide lien releases. They want to stay in first position. They will also want to see the full design plans and budget for what you are going to build. Their appraisers will generate a price for the finished property to determine if your loan is well under that price for the bank's tastes.
INSURANCE
You will need to purchase builder's risk insurance before closing on the loan. The bank will need to be listed as additionally insured. I only buy enough insurance to replace my building costs, not the retail amount. This insurance just pays for material lost to vandalism, fire, some natural disaster. Check your policy.
You can submit the plans and budget to the bank while the permit is going through the city or your legislative equivalent. Some banks may want to see an approved permit first, some may not. Ideally you can time the bank underwriting process to be complete at the same time the permit is ready. This is a tricky game, and rarely do they happen at the same time. You'll want to get the permit first if you get to choose, otherwise you will be paying for a note without a permit in hand, wasting money. Small local bank underwriting usually takes about 30 days to complete. Once you develop a good relationship with a bank and have performed several successful loans, that time may go down.
CONSTRUCTION CONTRACT
The bank will also need a construction contract between you and the builder unless you are the builder. That contract should do two primary things
1) Establish a price and schedule for the project
2) Set liability on the builder for insurable items. This ensures that the builder uses contractors and subs that carry insurance. These laws vary greatly by state, so make sure you protect yourself from an injured worker scenario. Each sub contractor should carry the insurance to cover these types of accidents, and your construction contract puts the liability on the GC to ensure that he hires contractors with the insurance required by your state's laws. Secondarily, you should carry a general liability policy for your company or yourself. These are generally not very expensive and cover you in a worst case scenario.
The construction contract covers a lot more than that, but those are the two key components I am most concerned with. I am not a lawyer and am not giving legal advice. Please consult your attorney to determine an appropriate construction contract for your business.
ENTITY DOCUMENTATION
You will also need formation documentation for your entity. If you have a partnership, the controlling partner will need to be clearly laid out in your corporate docs so the bank knows who they will be dealing with and who has what power.
Now that you've assembled all of that, your bank file should be ready for processing. Good luck at the loan committee review!
