@Shane Kelly - Awesome to hear another Old Brooklyn fan! 

Either a window or fan are required by code.

I am a former Real Estate Investor, my health was in question for about 4 years, and I have lucky and blessed to finally start to get back into the Game, I have never had any experience in apartment complex investing, my family have managed units for more than 30 years, that was my mother and she is not here anymore...in talking to the owner of the Complex, I see he doesn't have the effective managerial experience to do the job well enough, and the units are becoming deplorable, he has a gold mine, because where the units sit, right now the units, sit maybe within a mile to two major universities, one being UOH, that would be the University of Houston, and the next would be TSU, and that would be Texas Southern University, not ivy league, but top Universities, and the area supports it with what it cost to live in this area, that being said....He wants a ridiculous amount, for the units, but there are not cash flowing like they should, under managed, so we talk about a sale, and he is willing to sell, but I will need a strong partner to make this happen....Love to talk more to someone that has high net worth that could bring equity to turn these around....I have Commercial Financing that wants to paly, but I am not strong enough, with a a capital partner...Anyone?

On a personal finance note I am a bigger fan of buying your primary residence first.  

Fans and lights are 80's style. 

Fans and lights are 80's style.

But if **** hits the fan and this person decides to squat, you are screwed legally and you just lost your house for 6+ months.

sounds like you might need to call your insurance company, plus hire a company that specializes in remediation right away to preserve anything that might be worth saving, plus extract water, put in fans to avoid mold (if it isn’t there already). 

We were able to get a water restoration company out that same night to set up fans which stayed in place for 3 days until moisture readings returned to normal.

I'm also a big fan of using the HELOC for the purchase.
