(IMO from what I've found here and other forums).Let's put it this way, one of my crown jewels of a deal was done by knowing survey requirements that I could peel off existing houses that were on one plat that could be divided on thier own lots.

Grading issues, water leaks in the basement, water dams, leaky roof, drafty windows, boilers, furnaces, garages, retaining walls, sidewalks, failing plumbing, unsafe electrical, peeling paint on siding, etc....

Or even during the summer in especially hot climates (working on clay and tile roofs in Phoenix, for example).As an example, I spent the winter working on a project up north, where part of the buyer's lender's conditions for sale was that the house needed to be painted (it had really bad peeling paint), but the temperatures didn't get above 50 degrees for about three months, and paint won't stick in cold temperatures.

I used these Armstrong peel and stick squares at $.75/sq ft from Home Depot in a small kitchen and bath.

Before you start work in the basement, I'd suggest you turn off the hvac & mask any vents to the basement area.

Curious how it affects it or masks it......standing water in the attic, collapsed ceiling etc...

Keep your eyes peeled!

If the space rent alone is $250 then I would say a quick and dirty valuation is 7 X $250 x 60 = $105,000 but you still need to peel back the onion.

Now, I put the receipt in the correct category within a few days of when I get it, so I'm ready to go at tax time.If you know you will need some new tools or equipment to finish the work, keep your eyes peeled for sales, especially here on Labor Day weekend.  

Since there is no playbook for a pandemic , I went to my crystal ball , and all it said was " Put a mask on and get 6 ft away "  You can speculate , guess , predict and who knows , especially with the election coming up .
