Is her goal to be nice and provide some of the gains or reduce her taxes by trying to split income between her and her ex?

I may explain that while I’d like to buy/finance/invest in his property, I need to earn a certain return on my invested capital for the given amount of risk, and if not able to earn the return on the subject deal than I will on the next deal.  

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

If you have no idea what is going on with this capital call, then the bias should be "no" until you understand what is going on and believe that is the best possible use of your hard earned cash. 

At best, you will add another income stream to your portfolio.then your looking for someone like me.. 

This property gives me significant income, so losing it would be an extreme loss.

Start by deepening your understanding of CRE fundamentals, including net operating income (NOI), cap rates, and lease structures like triple net (NNN).

The only taxes I remit directly now are the tiny town tax they implemented of 1%.I just take my net income spreadsheet and calculate the 1% and give them a check.

Disclosure: Previous, current and future purchaser of Matt Scott's services.I have personally used Matt Scott and Incite Venture Capital to create my fixed income fund.

Mortgage lenders will qualify you for a higher purchase amount for multis than they would on a single, because they will count the rent you will be making on the other units as additional qualifying income for your loan application.
