I currently have tenants who pay through Zelle and with money orders.

The Motivated seller house is valued at 254,000 I offer to  am offering  to purchase the house at 75% of the appraised value which is $190, 500 and  pay closing cost of $ 7620 which is 3%.

Why would you even wait two months if you don't know them AND they did not pay rent?

Bought in 2018 and have over $500k in equity (through principle pay downs and appreciation over time).

Buy rentals OOS that pay for your life in FL, exactly what I do.  

Remember AirDNA includes the cleaning fee in their revenue calculations - you will have to pay the cleaners - this is a significant expense. 

I'm looking for alternatives as they've been increasing the price and I'm paying close to 70 bucks a month on the software. 

And when such a request is accepted, the tenant may be able to move out without paying penalties.

Now you need to figure out how to find deals and pay for them.

I use Venmo, CashApp, and Facebook to receive rents for those that want to pay electronically.
