@James E.We had some blank canvas on our house.Here's some things that went well, and some things I would have done differently):We love the 'pocket' style windows with recessed jamb looks, (ie: no trim) what I did wrong though, was to order those windows with the jamb extension on them , instead of having that done with the drywall crew. 

If you are living there a long time, here are some common things people over look: 1. window/door package2. waterproofing details3. building materials4. air sealing/ indoor air quality, energy performance requirements5. sound reduction6. site challenges / site advantagesThe average person chooses more square feet, and more expensive finishes over performance and durability. 

Essentially live in the 45/180 window and continually do 1031's with added leverage and increased profits to continue to grow and put have more rental properties.I want to have as much cash flow as I can each month and use that and opm to grow.

This includes drywall, paint, flooring, Demolishing, electrical, plumbing, roofing, windows, and much more.

Math works out to 21% Cash-on-cash return (see work below).It's in 32209, so it looks like it has a high crime rate, and there's bars on the windows in the pictures.

The other day i stopped and looked thru the windows and saw garbage & debris everywhere. 

If its a small 500sqft storefront-type space, usually a sign in the window along with advertising on craigslist and neighborhood facebook groups does the trick.

I can file for possession now, but how long of a window do I have to file if I want to wait?

I'm cancelling that part of the contract and will just put in window units instead (common in my city). 

At least some of them probably still run (or the seller was smart enough to take the window A/C units out of the windows for the pictures), but you might end up buying some A/C units soon.
