I would get an exterminator to take care of it since its a rental and that way they know you are trying to resolve it.

Also think about what can be damaged (tenants generally don't take care of the place as well as you would). 

Who pays when the resident knows they will eventually leave and stop taking care of the place? 

Also, don't complain about your offer not being accepted - just submit a better one or walk away - the seller doesn't care about anything other than how long its been on the market and how close to ask you are.

Quote from @Jason Burkart: Quote from @Theresa Harris: Whatever you do, I'd keep it in your name if you are the one paying for it, in part for some of the reasons others mentioned (if at some point she goes into a retirement home and needs to use her assets to pay for care).Are you able to pay for her home for 10-20 years? 

Also, I would check reviews and previous sales experience. 

As of now, I'm still up in the air...no major results to justify an overwhelming positive review yet. lol 

I do most of the putting out fires, hiring handyman, bribing people to not leave a bad review because they saw dust on a ceiling fan blade (lol). 

Also I dont know the state of the house ie is it completely derelict and trashed or what not, as previously stated i dont care about the house, just the land.

The goal is to create nice affordable living that members enjoy and take care of.
