We bought ourselves a furnished house with a giant pool, and also opened up a Short Term Rental.  

I'd may send a copy of the rent increase letter by certified mail but maybe not, depending on what all i'd learned so far.I'd always be respectful and positive and stress that the house isn't perfect but my duty is to fix what is broken and their job is to pay on time. 

The house is currently vacant as I'm doing some repairs and posting ads to get tenant in.

what is the fastest way to evict somebody from a foreclosed house?

. - It seems like the property was a duplex at some point and has house numbers associated with it.

The seller signed a contract that MIGHT have said “if anyone that looked at the house while we have this contract ends up buying your home you owe me a commission.”  

I'm essentially investing in one house per quarter.

We went with 2 of the wash towers in our STR and we are our cleaner's favorite house to care for - the love that they can get all the linens clean so quickly! 

I would stick to my normal business practices as opposed to accepting bribes to house unqualified applicants.

More than likely, it would end up being a house hack somewhere in the 300-375k range.
