Where an exchanger will purchase multiple replacements. 

Two years ago, the roof was replaced on the property and recently due to a leak, the roofing company discovered that screens were installed on the drains on the roof that voided the roof warranty.

We also had to replace two rotten walls and some rotten floor joist and subfloor.

Are you sure you are not just doing replacement therapy and you really should be buying a property? 

If you want to sell a property and keep deferring that tax by NOT recapturing the depreciation, you can do a 1031 exchange where the proceeds are held by a licensed intermediary for a short time while you identify and close on a replacement property.

Now my focus is on heavy rehab mix use/ multi-families that can be delivered below replacement costs and  $400/sf+ outsale new construction opportunities.

Even if your goal is to replace a W2 income, that only works long term if you are making money.  

For instance, not knowing what type of panels are on the naughty list in the eyes of the lender will trip you up during a DD period if you haven't underwritten your line item expense of replacing them.

Replacing a sewer lateral is easily a $7500 repair; it's probably closer to $10k, and personally I would have prioritized it over t+p. 

When people replace their old homes, you can possibly get those fairly inexpensively if they fit your spaces...Best of luck!
