Financing might be a challenge.I would recommend consulting with a attorney, loan officer, and CPA to discuss your specific situation and determine the best course of action. 

You should find out what percentage of the rent is being paid by S8 and by the tenant.Tenants have to sign the rent increase and some won't because they don't want their payment portion increasing.It's also highly unlikely a S8 office will approve the huge increase from $797 to $1300.- BTW: the $1300 includes all utilities being paid by the landlord.

Of course a visit to the county records office and -correct reading of the legal description would reveal that the tennis court lot was the one being sold.  

Its been a wild ride though doing all this through massive inflation and supply chain issue and Covid..  

I'd talk to your zoning office and see. 3 bed 3.5 bath in 1500 sq ft is pushing it. we build super compact and have a layout thats 3 bed 2.5 bath 1 car attached garage in Columbus Ohio.

We live, office, and Property Manage in Queen Creek and love it!

Then, just three weeks before closing, my largest commercial tenant—who brought in as much monthly revenue as all 25 mobile home tenants combined—announced they were moving to a location closer to their main office.

And, yes, there are years of data points to validate that just within my office, tens of thousands of dollars of wasted appraisal and inspection fees for deals (mostly not mine, thankfully) that had 0.00% of going anywhere but the "Loan Application Declined" bin. 

Send a Lease Violation Notice immediately - by mail with proof of delivery required (cheap date through post office) and or affix the notice in a envelope with his name on it on the door of the unit. 

We find that having the tenant pay for all utilities and taking the small hit on rent we are far ahead over supplying utilities to the tenant.
