Would it be possible to return their security deposit and sign someone else since the new lease doesn't start until August?

Explain they aren't paying 4 separate security deposits too,  I don't care about getting 4 checks I just tell them the deposit is for all damages and if one moves out they need to settle the damages among themselves.    

Buyer can pay to have them on for inspectionNo agent transaction fees allowed on the HUD, regardless if the Buyer is payingSeller will pay Seller’s closing costs and provide buyer with $29.95 PDQ Hazard ReportAny realty transfer taxes due will be the sole responsibility of the purchaserSeller will bring taxes and HOA current through closing10% deposit on cash offers (Cashier’s Check)$1,000 minimum deposit on financed offers (Cashier’s Check)60 day MINIMUM escrow period.

The tenant is asking us to pay the $500 deposit.

In a rent to own you can charge premium resell price (i.e.190k) , you get a deposit that lowers your cash advance , you collect the majority of the rent (no vacancy/turnover and typically no maintenance costs) ... if you have bought at 105+20 rehab+ 20 financing and closing costs costs and unplanned you total 145... if you sell even at 180 to a rent to own and get a year of monthly payments that give you approx another 10 net, you spent 145 and made 190I hope this makes sense to you... in order for my rentals to work I need to charge 1k rent for 50k house (or 2k for 100k house)...

The tenant is being helpful about everything.Can the tenant start the evict process (she offered to pay for that...and I have a security deposit), or should I just wait to see what happens, or start eviction?  

Both had extensive legal fees and hemorrhoids from sitting in interrogatories, depositions, and trial.

Non-refundable deposit to lock in the option.

I'd give the non-paying tenant notice for cure,, to pay his electric bill or I would file for eviction.Any electricity he would owe me for, as in the interim I would include on his move out security deposit charge sheet.. 

Here is my question:  Should I just refuse to resign the lease or just ask for a bigger security deposit with renewal (like $3,300?).
