The relationship with long-term tenants we inherited two years prior had been sliding sideways for some time - their unit was the only one we had not renovated and they felt entitled to a fresh home.   

Do they have any windows?  

Checked your site, nice info on places like The Villages, though having to use a bottom slide bar to read was a minor irritation. 

Depending on the extent of your rehab, you can buy used windows, doors, vanities 1st and frame around them.  

If you are unable to accomplish them within the time window, move on and come back.
