She's playing you then.

This is where experience comes in to play. 

There are legal, tax, and coverage issues that could come into play.  

If so, what part of the puzzle would you like to play? 

@Ian WalshThanks for posting Ian, I have played around in the Boston area sandbox a bit.

Good call on multiplying the numbers by 1.5 - always good to play it safe.

Debt snowball these properties while fund Roth IRA, 403b after appropriate CapEx/emergency funds for the properties.How has this played out so far.Got pre-approved for an absurd amount at the moment, but will not use all of it because that is contingent on double full-time employment.Somehow managed to look at three properties in December, only had four days off, all of which ended up requiring cash buys due to disrepair, estate sales, foreclosure.Currently networking for hard money, private financing, while continuing 65-80% savings rate.Will reduce my days of work, get some ski days in the winter and mountain bike when its warmer.

There is no power to run fans or dehumidifiers etc.

I am helping my mom manage her portfolio which is mostly intertwined with my own since she has capital but no borrowing power and I have no capital but have borrowing power.

There is a crappy 2 stall garage out back no one is using with no power currently run to it, could potentially add monthly storage fee or rent it out to 1 of the tenants for x/mo.
