Quote from @Devin James: Gross Margin is an important calculation for developers/builders.Gross Margin = Gross Profit / RevenueWe shoot for a 20% gross margin on our New Construction HomesReal #’s:Home Sales Price: $374KClosing Cost: $18,700Cost of Construction: $258KLand Cost: $30KGross Profit = $67K$67K/$374K = 17.9% Gross MarginCame slightly short of our goal of 20%Homes Values and Build Costs are constantly fluctuatingI wish we had a crystal ball build larger homes. average new build in our market is 2200 square feet, 4 beds, 3 baths, 2 car garage and sells for 515k. construction costs lower if design is good and find the median or average home sale price and push that up. my guess is you built too small. 347k is cheap. we target 429-479k price range in columbus ohio for single family homes and also only purchase close to urban core where premiums are 20% higher and we build smaller like 1500 sq ft where price per square foot goes up.

If you see at least a few zoned in the designations you mentioned above, that's potentially a good sign that you can get support from the local Alderman's office, and approval by the ZBA (zoning board of appeals), to rezone.

Your focus on the Dallas market and Fix and Flip projects sounds solid, especially with the DIY approach and having an interior designer on your team. 

But I also like DIY design and drafting so YMMV.

The FHA 203(k) loan is designed for owner-occupied fixer-uppers!

Even a single family builds can vary significantly based on site conditions and required structure/design.

In tip top shape both in the mechanical systems, design, and upkeep2.
