This program has income and area restriction. 

Likewise, your new lease may, or may not, be permitted to restrict rights currently afforded the tenants under the default ("at will") lease provided in the tenancy law.

I am in process of a 44 unit age restricted facility in the Winnipesaukee area of NH.

So, while my research did not find any rental restrictions for STRs I did not discover that they couldn't give me a business license (before we bought the house.)After talking with the City Planner about the situation he told me I could go through the same process that a hotel or B&B does (approval process for Certificate of Conditional Use) but it basically comes down to a City Council meeting which is a public hearing.We discussed the fact that there already were people operating STRs in the city (and obviously not paying taxes to the city since they would not have a business license). 

When you get new orders to a new duty station you can do it again (But you can only do it twice and there are restrictions).  

Any suggestions on how I can finance a deal that is under these kinds of restrictions??

They may have restrictions in terms of age and size.

It's true, if you opened a Solo 401k directly with the brokerage, you would not be allowed to invest into alternative assets and there would be a lot of other restrictions.

Where you can state that the tenant is allowed to sublease (with your approval or whatever restrictions you want to put), and then state that any sublease requires a move-in fee of $___.

I am wondering if UNCLE is going to do something like they did in the GFC were they restricted lenders from taking defaults from owner occ..
