3 - If you sold, and had $80k to work with, and used it as 20% DP's on similar properties (that would be 2 properties), how much cash flow would you be getting...compared to above?

Make sure you know what comparable properties are selling for, and what renovations are necessary to get top dollar.

@Even Pickvet-Hall No last year tax return should have higher and YTD should be higher in gross compare to last year comparing with your w2 income.

All they care about is who's the trustee and do they have authority to sell the property. 

And you can always require your renters to carry renters insurance.2- Landlord tenant law is state-specific, so you would need to research codes or reach out to the state real estate authority or your local metropolitan housing authority (MHA)....they are usually a good resource.You would need to check with your county auditor to see if there is a requirement for a "rental registry"...this is county specific...or could be related to city ordinance as well.

So I called the attorney who has the files to see if he has been given executor status and was told:1. it's an old case2. he does not have the authority to sell the propertyThen I called the courthouse to see who is the administrator over the estate, and was told that they have no record of the mother's death! 

The reason being they know the project and willing to work with you with better interest rate and lower down payment compare to online lenders for condotel.

I think it's about the most space efficient you can get, plus there are likely energy efficiency benefits(or at least utility cost improvements) compared to your current set up.

Since I am a numbers person, I like to look to be able to compare scenarios to help build my strategy, but I have found it difficult (even hired a wealth strategy consultant) and have not been able to find anyone to give me such examples and scenerios.

In the owner finance, you take a fat down payment, so I guess more money upfront in that scenario, but is it more lucrative in the long run compared to rent to own?
