Typically, the STR property tends to be priced at 10x of the annual gross revenue, so let's assume you buy a house for $500k and you can get $50k a year in gross revenue. 

You could tell them to cancel the listing and you will find someone else to list it after a month not 4 months (the market take is subjective too, all dependent on what your house has compared to others, where it is located, the size of it, and so many other factors).

Once you are on site you can decide if your $20K should be used as a downpayment on a double to house hack (to stop renting), a single to just stop renting, or a single to lease out.

We had a house on the Deschutes River in the subdivision we were doing a spec new construction house in.

I truly believe she had a medical condition and shouldn't even live in my house, should probably live in elderly housing or the like.

I think this will even out your space in the house.

I'm currently in a rent to own house we are moving out of and will be renovating and renting.

Only in this house your mom happens to be the tenant. 

The buyer of course believing he had purchased the house paid a visit to the tenant, who of course called me.  

By this time, I realized Chris was wholesaling the house to me (unlike the other houses on the tour) and charging me to manage the project.
