When I add my other parameters the grand total is 299 leads with 1-100% equity.Am I missing something? 

This is a pretty robust service that provides a grand amount of information properties (legal / homeowner / tax / title), including some county-filed documents and file numbers for others.  

He would typically put a few grand into it and then resell owner finance.

That brings up the question of whether I should just stick to the 100-150 k range and put 20% down on a conventional mortgage because I have roughly 30 grand to put down on the property.

Does anyone have any suggestions on where I should earn my license and if it'd make a difference overall in the grand scheme of things?

But, here are some quick examples:AZ - 4 plex in Casa Grande for $160k with $2400/mo gross - that's 1.5%AZ - unoccupied 4 plex in Globe for $100k that needs $10k in improvement with a rent potential of $2000/mo gross - that's less than 1% (if you can even rent it out)AZ - PHX metro area in general was even less encouraging.

Also, yearly revenue means little in the grand scheme of things, it's really your Op Ex ratio that is the silent killer with STRs so be sure once you have a yearly revenue you are comfortable with, truly dive into the operating expenses involved.

I am originally from Grand Rapids, MI and have been starting to evaluate rental properties in the area again.

Kalamazoo and Grand Rapids are safe bets too.
