Quote from @Clayton Silva: I am familiar with the area, happy to help in anyway I can, a lot of stuff like insurance or tertiary questions I can probably get you plugged in with someone more knowledgeable on those things. 

For example, maybe you will get to 10, 20, 30 houses and then find an owner who has a large portfolio and all of a sudden you are at a high door count and now need to hire, need to build your policy binder, and all the other stuff that comes with running a business.

He even chatted with me through this forum (Bigger Pockets) and was very encouraging that you can even do it just with free stuff out there.  

I don't know if credit unions can ever do this stuff?

Meanwhile, gross rents of $1,800+ for 3-bedroom single-families is an achievable figure, so it’s possible to generate cash flow if you lever modestly.There’s a bunch of other stuff that’s worth highlighting—the economy, demographics, neighborhoods, new construction, and more.

Paying those things benefits you because they facilitate STUFF exiting the house. 

I wouldn't consider it a heavy negative unless the street is super tight and parking is hard to come by or if the street is very steep/busy.The more desirable dense city neighborhoods it's almost kind of expected and off street parking would be considered a luxury rather than a necessity.If you get out into the suburbs I would say it's more of a big deal since more rentals have off street parking or a garage there.

It's not to say I don't get sick and tired of stuff, but if it is worth it, I will continue to bang my head against the wall.
