I am new to the game, but hoping I can be a great connection for many people just looking for the right partner/match.

I believe that both patience AND readiness both need to match up and align at the same time. 

Taking the check, depositing it to my bank, then simply regularly paying the mortgage down seems like the most common sense thing to do, but doesn't seem to be the most financially responsible thing to do when tax season comes around.Would having an LLC and depositing the check into a business account make more sense?

Setting aside some reserves at closing and making monthly reserve deposits will offset the risk of having a few down months. 

Tenant texts me today saying bring security deposit to final walkthrough or he can't move out.

I know, it’s rude of me to do such a thing, but had no better idea what to do.Well, the thing is that the guy owes to his bank thousands of dollars as he kept depositing money to various online casinos.

Note, only if the turnkey supplies properties that match your target tenant pool does buying turnkey make sense.

If we don’t they most likely will make them leave before closing so the seller gets deposit due to them destroying the place.

I want to get in on str and I love this market, but at the same time, I don't love the idea of putting down such a large down deposit, even at 10%, and having a $3,000 monthly mortgage payment to worry about.

Frequently, C Class properties look great on paper, but the reality does not match up.
