Blood gets thick and the worst part is 10 years later there are new voices in their ears, telling them all kind of crap and filling it with all kinds of ideas. 

Happy you joined the party.. how soon do you plan to start crunching numbers on a potential deal?

@Eamon ConheadyThis sucksFor anyone reading this, it’s important to always use a 3rd party escrow company and send any monies to them.

As far as benefit to the seller goes, @Matthew Paul I think you are probably right on the money and regardless of whether they would have preferred to stay in this house rather than move, it is likely providing them some excellent cash flow; and I'd be hard-pressed to come up with a deal that serves both parties better than the current situation. 

However, you can make changes as long as all parties agree.If the tenant agrees to removing certain clauses, or starting with a new lease, then you can move forward.

Or do you have to use a 3rd party site to keep them updated and then spend more? 

This includes credit, criminal, and rental history checks for all parties.

Yes, I am a property manager but even I use a 3rd party PM for my properties that are out of state.

No Sweat Equity: Repairs or maintenance must be done by third parties and paid for by the IRA.4.

Whether that is a sale to you or a 3rd party I don't know but the threat alone may be enough for her to sell it to you.
