[quote=svelte]There is no way you’re gonna get a/c installed before the end of this hot season anyway.
And chances are she’ll be on a different tangent in 12 months anyway.
If it were me, I would get the quotes, tell her if she pays that amount up front you’ll have it installed, and wait. I bet she never comes through with the cash. Actually, I’d bet a pretty good chunk of change on it.[/quote]
Thinking about this more I would amend it slightly. I would make sure that in writing it states she is paying for air conditioned dwelling space, not for installing an air conditioning unit. I wouldn’t want there to be some legal way she could take the compressor, etc with her when she moved.
I’d also make sure there is nothing that specifies how long she is entitled to live there to recoup her money.
