If the property they are purchasing is greater than what they sold then anyone can take title to the additional percentage as a tenant in common. 

But I began this reply with IF, because if they are all cash-flow positive, I would personally not seek to pay any of them off early (depending on your age), and instead save that money to put towards obtaining additional properties.

This can offset your W2 income and make money that way.

Qualifications typically center around whether the monthly rental income can at least break even (1.00 DSCR) with the monthly PITI.We would simply need to know the following information to determine eligibility, interest rate, and loan terms for DSCR financing:o Purchase or Refinanceo Property Addresso Monthly Rental incomeo Annual Taxeso Annual Insuranceo Estimated Credit ScoreThe documentation is relatively light as well, compared to a conventional loan underwritten to your personal income/taxes/debts.▪ Entity documents ▪ 2 months of bank statements ▪ Photo ID ▪ Lease agreement (refinance) ▪ Sales contract (purchase)

So, both my wife and I are full time W2 employees and are in the 24% tax bracket, and I came across the short-term rental loophole which sounds really amazing for taking write offs and using them to reduce your W2 taxable income, but also equally difficult to qualify for, unless you are within a short driving distance to your property.  

Maybe focus on getting that income up along with paying debt down.

The very high income investor typically 700k a year and up income with job or business who is busy but gets googly eyes looking at some pro-forma high return and have no clue what they are looking at.

In addition to the good advice posted above, the two biggest flags I've come across:1.

That would piss any person off even in the high income realm.

For example, I have been informed from a couple of banks that even though my current Airbnb totally offsets the mortgage, they will not take the income from the property towards the DTI calculations but rather take the gross income from the Taxes filed and consider the mortgage amount as an expense, which was hard to understand.
