Rehab Cost Estimates
Hi guys!
I have a question for the experienced wholesalers out there. How does someone, with no construction background estimate the rehab cost of a house.
I know J Scott wrote a book on it, and I will likely pick that up, and I have read in another book, that making a spreadsheet (or having one available) with all of the common things found in each room is a good way to start.
So if the kitchen needs (for example):
-new countertops
-new tile floor
-new backsplash
-new stove
I would just measure everything, write down the materials that are already in there (i.e - granite countertops), and price it out at Home Depot or something?
As for the labor costs - how do people usually go about estimating that? I feel it could get very expensive, and/or time consuming having a bunch of different contractors come out and give quotes, or even more expensive, a GC.
Any input or methodologies on this subject that you all have employed succesffully would be so much appreciated! Thanks!

@Rich Wahl - Everyone may not agree, but here is my honest feedback. Don't start with wholesaling. That's like asking someone with no automotive background to estimate the cost to fix a car that they found abandoned on the side of the road.

With that said, here would be my recommendations to answer your question.
- Pick up both of J Scott's books. Read the rehabbing one first, then read the estimating one. J does an extremely thorough job of detailing the rehab process and every potential aspect of a renovation.
- Create a detailed spreadsheet (maybe using J's book as reference) for every potential aspect of a renovation. Call around and get quotes on some of the major ones (ex. cost per square for a roof replacement, either tear-off or 2nd layer). Put these in your spreadsheet.
- When evaluating properties, work backwards like most rehabbers do. Determine the ARV, multiply by 70%, the subtract out all of the rehab costs. Multiply your estimated rehab costs by 20% for your fudge factor. If you really want to be great, actually have some contractors come out to the property to give you quotes.
- Now that you have a vetted deal, start marketing it.
Again, I would recommend that you not start with wholesaling if you have no experience in renovations.
