Impounding someones car sitting in a public parking space would likely get a hard scolding from a judge somewhere, so even if it worked a time or two, overtime it would be outlawed IMO.

These leases should also be recorded in the public records.NNN leases are commonly used for commercial transactions.

@Joshua Tikal College rentals are not something we specialize in but the experience I have had from managing thousands of rentals over the years is that everyone starts out wanting to provide good housing options for the general public but lose sight of the fact that this is a business and please run it that way.

BTW the Sheriff doesn't sell most foreclosures in Colorado, it's the Public Trustee. 

If you don't advertise it publicly but offer in private, you don't promise anything.If you do offer the premises for rent publicly, it has to be compliant with Fair Housing law.It's a slow time in rental business and if you never find who are you looking for, are you willing to take on financial losses because of that?

This includes Public Housing Agencies and Multi-Family owners.

My concern is trying to break out of the local perception of the adjacent town and trying to pull b class tenants in a c class area again only due to the reputation of the town as a whole.

you may be running into the negative perception of wholesalers who tie up property with no means to actually close. and if they cant assign the contract they walk . 

I am making no judgments, but it usually takes quite a bit for someone to get this public with a dispute.

If you have plenty of activity but no requests to rent, the cost is too high in perception to what the tenant is getting or giving up.
