I had a property under contract. . .The seller refused to allow me to conduct a walk-through with a potential partner. . .Can I terminate the contract and be refunded earnest deposit on the grounds that "Buyer may make two pre-settlement walk-through inspections of the property (Section 12.A.2 of the PA ASR)"?

During eviction proceedings, we came up with a settlement that she would pay an extra 200/month until she is caught up.  

Well, at the closing of your sale, you very likely signed a document that basically says that after settlement you will cover any expenses that would have been your obligation in the event that such expenses come to light.

As long as you settle on the property before any pending tax action is final, you would just pay the back taxes at settlement.

If not, you likely must honor current lease terms unless tenant agreeable - read lease as it may have early termination agreement. 3) your contract and/or settlement statement should show security deposit transfer agreement.

You panic, negotiate a settlement for $5,000, and they do this over and over again.

I've never heard of a flat fee settlement company in Florida or anywhere else. 

With an attorney handling the eviction, you can not only ensure proper handling but also take advantage settlement agreements to prevent having to restart the process if the tenant were to default again and get automatic final judgment when the tenant defaults on the settlement agreement. 

You cannot assign a financing contract in your transaction where you obligate the seller to finance to a third party without their specific consent with that borrower.You're also  not a mortgage broker, compensation has nothing to do with it and you're brokering a mortgage as a straw man (wholesaler) type arrangement.Side deals (bones and steaks paid later) outside of settlement is a violation of TILA, Dodd-Frank, the Tax Code and ALTA, Things can happen in life that expose such transactions, things beyond anyone's control.

A final settlement statement should be agreed upon to ensure no discrepancies.This process ensures that the transition is efficient, minimizes disruption for tenants, and allows you to take over the management of the units with all the necessary information at hand.I hope this helps, and best of luck with the transition!
