Being prepared for these hurdles can make all the difference in achieving long-term success.

Waivo has a different but similar product they sell directly for STR.

Sounds like things have changed a lot since 2016, and it's helpful to hear from someone who’s actively operating in the area.I completely get that this is a different market dynamic.

I figured the PM would definitely be local to the area of the property and would need different PM's for each area, those were just the areas I'd like to invest in. 

There are a bunch of different figures associated with this decision, such as new interest rate, old interest rate, cash flow of new property etc, but I'm having a hard time getting my mind around how to analyze the decision mathematically.  

These are very different than Subject-To, as the loan actually transfers to your son's name, and off the seller's name. 

It also gets treated differently in Texas vs CA vs AZ.

PMs are busy - if you email a PM and say "Hey PM, I'm looking at 123 Main St. and I think it will rent for $1500 a month, does that sounds right?"

Last thought (mainly for future readers), you may be talking about the 1 year FHA history if you have variable income.

This is a pretty critical difference.
