We are going to be empty nesters in a few years and would like to quit or jobs and move to South America and using the revenue to supplement some of our income.

If I own a property, I can essentially use it as a savings account...

They essential strip the offending party of their license as apart of this process.

You not only consider the number but it is essential that you consider the % of their credit limit they have available.

Then pick  your best quote.Chances are almost all lenders are going to quote you essentially the same rate and/or will factor in discount points or lender credits to raise or lower the rate. 

update on deal: the rent rolls for the property were extremely low ( 6 unit complex gross revenues of 4200) it would have been negative cashflow property and there were long term contracts ( any where from 6 to 10 years ) in place that we had to honor upon purchase.

If you can do this, then it is essentially the same scenario as selling your home and buying a multifamily unit.

However, if you feel more comfortable having someone handle all of the management so that you don't have to worry about anything, start with your network of family/friends and see if anyone would be willing to help you manage for a percent of your rental revenue.

The method that I have been experimenting with at the moment is essentially taking a pre screening Google Form that I got from someone on Biggerpockets a while ago that I have been sending to everyone that reaches out as the first step before they come in to see it.

My long term goals, or 5 year goal right now, is to start by purchasing 2-4 homes per year over the next 4+ years, and pay them off one at a time from the revenue.
