While buying one that’s up and running might seem a good idea - paying for speed - if you’re not quite ready, sometimes the best deal you make is the one you don’t make at all.

How much do they want you to to pay, to pay off one of the mortgages (or both of their existing mortgages)? 

While short-term rentals in areas like Kissimmee, Florida, can pay for themselves and offer lifestyle benefits, the ROI typically doesn’t match what I see from my traditional portfolio of long-term rentals in North Texas.That said, short-term rentals can still be a great choice, especially if you're drawn to the area and the opportunity to combine personal use with investment income.

Hopefully the current occupied units are paying every month.

We typically pay somewhere in the range of $3500 for a new, basic furnance, including install, if there are no other modifications to the system required.  

Do you want to be passive (ie give your $ to someone and they pay you interest, or you put the money for the opp and get equity, etc)3.

Quote from @John O'Leary: Hey Remy,I'm not familiar with that program, but I'm a firm believer in paying for education. 

Now, you need to figure out how to find deals and pay for them.

One of the first deals I had (multi in an up and coming area) my buyer was paying cash and the deal was solid.  

To answer your question @John Thedford, PPR's current fund pays 12%.
