Rent I could probably collect $2000 a month.

I'm tempted to go with $7.99/month of "Quicken Business & Personal". 

There is the Experian Boost that adds monthly utility bills as credit and various apps and facebook groups.

Now, this tenant is saying that they don't remember any agreement and thought they paid month to month and could leave whenever.

We’ve been trying to onboard with AppFolio for the past two months, but the process has been incredibly frustrating.

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

But as far monthly payment you could easily buy a house in a cheaper location have less roommates and the same monthly payment or the same number of roommates and a lower monthly payment.

There is no excuse.Is she on a lease or month to month? 

With 4 rentable rooms (including the basement), I expect to generate $3,600/month with full occupancy.

I have a couple STR investors do this here in the winter months depending on the events coming to town
