@Christian Bors  and if you vette these guys  and like Marks says he has been in transactions that they are the funding source so there is one Top local Broker validating that they actually do fund transactions.So once this is done.... your sitting there focusing on a measly 800 bucks.. heck we blow that on dinner.... for 800 dollars you could jump start a whole career..

Todd: With a roof that is only 2yrs old, HOPEfully you still have some warranty from the Roofing Company that installed it.

It costs them nothing to fix it and you have a year warranty so you’re not getting a mechanical discount. 

I also validate my right to record the Deed by having a purchase option in the JV Agreement.

It all comes down to Costs... but keep in mind that a full roof replacement, should give you a new Warranty on it, and extended lifetime and lower insurance costs too!

We use delta fixtures as they have warranty a couple times even when it wasn’t thier fault.

Is there a way that sellers should validate this information?

Tax deeds are given without warranty or covenant of any type; it is the purchaser’s responsibility to determine what, if any, interest in the property is actually being purchased.

I think your points are all valid and you're definitely more savvy than me lol.

In light of the fact that the leases are a scam I would not feel guilty but would still try to prove the leases are not valid first.
