I was wondering if anyone had ideas on how I might be able to attract more tenants who are okay with having this type of policy as I know it might be a bit of a niche market, but I'd love to hear any suggestions.

Quote from @Jaren Taylor: Quote from @Chris Mason: If you have the ability to market and raise money, then you secure the down payment, and do the normal commercial mortgage process. 

You won't find one PM that hits all 3 markets as there is a pretty decent distance between the 3.

The original six month tenant I had extended the lease 9 times and stayed a total of 5 years, paying me about $15k over market rent annually.  

A sellers market in general.

Value: I am paying current market value. 

On my new builds we hit the double cash on cash in certain markets sometimes its only 50%.

Ive invested in the Boston & DC markets for 22 years now.

Look for motivated sellers off market and market via cold calling and or direct mail, geofencing, advertising and the like.A good wholesaler is as @Ericka Parrott mentioned, direct to seller, did good underwriting and can deliver an actual "Deal" whether buy and hold or flip. 

These will be markets where housing is affordable for both residents and owners.
