In evaluating seller financed notes, there is always a balance between redeeming and non-redeeming factors. 

Government assistance/tax credits are of course a consideration that is factored in to the cost/benefit analysis of any form of new energy generation, as all forms of energy are heavily subsidized and always have been, long before solar entered the equation. 

When evaluating markets for rental properties, there are a lot of factors to consider: population growth, employment rates, rent to price ratio/GRM/Cap Rate, rent trends, vacancy rates, etc. 

This is primarily due to two key factors: low inventory (leading to tight margins) and high interest rates.

You'll have to factor that into the holding costs as well. 

Ask an attorney for the cost breakdown, factor in holding costs, assume they'll do more damage on the way out and then ask for a bit more for the headache.But again, especially with no experience with evictions and it sounding like a mess, I would be very tempted to just walk if the tenant is not going to cooperate. 

Some of it can be temporary, but ideally you'll want to be in markets where it can be sustained (ie. have barriers to entry). 

The reality is you need to move off a few factors---fast solutions have slow problems, due diligence, have a healthy safety blanket reserve wise. 

But there are bunch of factors to consider there. 

Should be within the last 6 months sold ideally within 1 mile.
