I would include servicing costs of the loan and licensing costs.

There's also disclosures in there that have to be included in your lease paperwork.

If anyone could include what to look out for in a good deal and a bad deal

The costs are not trivial, but they are less than you would pay for a nice used truck.One of the main reasons I am considering this route is the leads that are provided.

However, this would be pathetic RE returns and more so for out of country and it includes the far from certain appreciation.I suspect you will need to offer the 50% stake at a significant discount otherwise the investor could just purchase without a partner.  

Just ensure to complete necessary due diligence - this can include, but is not limited to, title search, property inspection, appraisal and/or survey. 

They'll want all the money spent on the main house, lenders kind of ignore ADUs it's weird. 

Please advise.ThanksMel I'd recommend a local Independent Agency that has access to multiple markets including surplus lines

Principal balance currently at 314kProperty Details: It's essentially a "2-in-1" property, with the main unit rented out for $1,900/month and an attached ADU bringing in an additional $1,200/month.

There are at least two I found on a quick google search including Central Indiana Real Estate Investors Association (CIREIA) and INDIANA REAL ESTATE INVESTORS ASSOCIATION.
