The clients I've worked with had issues with parties for their larger homes and ended up leaning towards traditional rentals or mid-term.

That part is normal for commercial mortgages; 5 year maturity is common, and 2019+5=2024 is why many are expecting offices to have a rough couple years.Net operating income (NOI) is net profit before the mortgage payment, and determines how big of a mortgage you can get. 

It makes life much easier for all parties. 

Do the 3 parties tax you at once: X, Y, and IRS?

Issues like this can take a while to sort out depending on if they can determine where/when the error happened and if there is any party or title insurance who will compensate someone for the error.

I'm in the minority here, but I prefer not to have a third party vendor handle rent transactions. 

The hardest part is to start in my opinion.

In the future, always get an independent third party opinion. 

It is important to understand the prohibited parties, which are family members your IRA funds could not be lent to. 

Maybe the mentor is the missing part?I
