Do I need to have them sign a new lease to raise rents.  

Once you read the explanation below, you will understand how REALLY bad things can be if you don't get the letters but go through with the purchase.First, the owner/seller should have a clause in the lease requiring tenants to sign (or object to in writing) tenant estoppel letters if presented to them.

Find anyone really to sign a quit claim or make them up, have it notarized (the notary's name is not on the GA notary list by the way), and then buy a property for $90k, you take a $8k hit on the fees, then you get back the overage paid to you by the city. 

Before signing up, i asked if I could talk to a FS student to so they referred me to a woman who had good things to say.

Whatever you do, please make sure that you get something signed saying that are completely gone and have no claim to any possessions they left behind. 

Several things to consider: 1) One of the main purposes of segmenting your assets into separate LLC's is so that your personal net worth or equity in other business ventures or properties isn't exposed, so unless you have a high net worth or a lot of equity in a property, it might not be worth bothering going the separate LLC route, especially when it restricts your financing of the property.  2) Most any commercial financing you get from a local bank for a small property is going to have recourse anyhow and require that you sign a personal guarantee, so you're still personally on the hook to the bank even in the case of a commercial loan.  3) If you're a newer investor and buying a deal that's tight on cash flow, or if you don't have a ton of cash sitting in the bank already, your greatest risk factor as an investor is your investment failing economically due to poor financing terms or not operating the investment properly, not because you get sued. 

Thank you for the pointers, having the tenants sign the septic portion is a grey point!  

@Gary F. they all sign one lease and pay together.

I see 3 days ago a charge for a whopping $390 was charged from BiggerPockets to my card. It was an automatic membership renewal with zero notice to me to decide if I wanted this or not. How do I get a refund?

My question is since a lender is involved and I will be drafting up a contract how do I protect myself as to once I hand off the home he doesn't end up pushing me out (there is no sign of such and there is trust but this business)?
