We were able to replace the siding and the roof on the entire house, new A/C unit, rehab the entire interior (fixed foundation, new floors, paint whole house, new kitchen, new baths, install ceiling fans, reglaze windows, termite treatment, etc) for $50k.

I'm always a big proponent of house hacking if you are able.2) Sooner rather than later get into a job that has no ceiling on the income/something where you aren't just trading time for money.

It is a huge square footage space, but one side in particular had no insulation from an earlier ceiling "repair".

I am refinancing, and the new appraisal came in at $360K and only 1230sqft. when I called the new appraiser, they stated that the 6'4" ceiling in the two attic bedrooms disallows its sqft too count towards the living space sqft.

I cannot tell you how many times tenants TRASHED entire house, put dog feces on ceiling, destroyed windows/doors on purpose... it was horrifying.

Okay so I've created a 4th option, which would be to have a ceiling mounted range hood.

This house needs new paint, floor, popcorn ceiling removal, and a new kitchen and bathroom if a flip. questions:1. how much is it to replace windows?

It has a full unfinished basement with tall ceilings. 

We were doing this huge project and found a bad beam in the ceiling.
