What is the single best 1st rental purchase?

[Andrew Hoelzel]

A mortgage client of mine asked me this: 

"Please ask your network this question for me as I lean into r.e. investing:

1.If you could do it all over again, knowing what you know now, what kind of investment property would you buy for your 1st unit(s)?

2. Why would that be the type you'd by now, even if it was not your personal first?

3. How would you measure/analyze that deal i.e. what factors would make it a winner for you and make you pull the trigger?"
