With that in mind, I’m considering purchasing four rental units over the next four years to build a stream of income that could help supplement my retirement by age 68.The challenge I’m facing is that the deals I’ve come across so far don’t make financial sense.

The interest rate isn't that huge of a difference between the 15 and 30 so worst case scenario if you have the 30 year option is you start paying it down on a 15 year timeline - sure you'll pay a little more in interest over the 15 years, but it will have been worth it if you bought another house.

I'd love to help by sending over my investor friendly PMs, lenders, GCs, etc.

This approach avoids downtime and lets you start earning right away.Future Bookings:Taking over bookings can get tricky since Airbnb doesn’t allow direct transfers between accounts.

I feel like those lists are sold and resold numerous times over and over again for the same data.

If it wasn't housing, food, or transportation, I didn't spend money on it. 

I'm looking at rolling over ~350k into the replacement property. 

People who fail to keep good tenants and turn over every year, they lose. 

I have a great one in Kansas City for over 15 years that I've used multiple times (only auto loans however), but hoping to branch out locally as I begin my investor journey in Arizona. 

Based on the development expected over the next decade, I believe it's a great area to invest in.
