I know this is a differing topic on the forums, and online in general, but having the legal background/education and knowing estate planning concepts you'll realize it shouldn't be.  

I love this concept of a developer working directly with a rural municipality to build affordable housing.

They are grandfathered in, the property was built prior to those standards.

You have set your standards.

@Kash Tacke I'm a big fan of ADU's in general especially here in the mid west, yes you could potentially be on the front of the wave, but housing density is the solution to the affordability issue, anytime you are investing with affordability in mind is a great strategy to me, and sound like there are some incentives or at least supporting winds form the local city, that in itself seems like it would be worth at least approaching an architect or contractor to bid up some plans or concepts to take tot he city.  

What other concepts could be added to list of options? 

If they are CF positive then they will not cohnt against your DTI but will improve it...that's standard conventional guidelines barring a few exceptions.

I've exchanged our place with another host by on a 1-1 bases.Host share seems to have an interesting concept of exchange available nights but within 5 days.....so what typically is not rented.

I’m new to private money lending, so while I understand the concepts in principle, I’m still figuring out how to identify and connect with these investors in practice.To clarify, I’m targeting 6+ unit multifamily properties, and private money is a way to scale my expertise from smaller properties into larger ones.

The standard legal procedure, as far as I understand in NC is the landlord must make reasonable effort to re-rent the property (which I will), and any vacant time till new tenants are found must be paid by previous tenants.
