The advantage of "rent to own" is that typically you're selling them an option to buy the property that they can choose to exercise or not.

Because you're saying you can pay them full value whereas everyone else has been "low-balling" them in their eyes, they'll likely ask you, "How does that work?"

This exercise may enlighten you (and if you want to post your result, I would be interested but I am confident it will be over $1k/month because we buy semi regular, including some poorly timed such as 2004, and they have all appreciated over $1K/month (I believe our worse is $1.6k/month over the hold period)).  

This may be more of an odd ball question.

When my agent reached out, the sellers said they have only gotten low ball offers and would consider accepting if they got an offer above the list price.

I don't blame Landlords for exercising due diligence when hiring a new property manager. 

Something big with something of size in it,  like a stress ball or a payday.  

@Taylor Thompson Congrats on getting the ball rolling.

Without getting too personal, there are family and financial and factors here that make me think, if I had a crystal ball, I would not be surprised if she stayed here for four or five more years.

Mostly what I'm saying is the best way for you to get an idea of what you are looking at is to have a builder walk the property with you and look over preliminary plans and give you a ball park of what you can expect.
