Any one have any insight on if this could pose a problem and guidance on how to proceed? 

Trying to figure out how to proceed I have an SCorp already that was just created, I will have to see if its serving as an LLC as well if thats a thing?

I was about to start foreclosure proceedings, until he sent me this recent money.

You should only proceed with appropriate protection in place, which includes a significant down payment of 10% or more, a solid mortgage, and an attorney prepared to help you with the foreclosure process.I don't see any benefit to your buyers, but if they are willing to pay you 10% for 20 years, then go for it! 

WAIVERS: Our acceptance of Rent after knowledge of a breach of this Lease by you is not a waiver of our rights nor an election not to proceed under the provisions of this Lease or the law.

You did not do business with them and are still here bashing them online.

one BIG problem that we've seen from one HML to another HML is that during bankruptcy proceeding , some of the HML guy can perform the job by chasing all entity involved, while some other fund just give up and write-off the loan, so it's more complicated.For each fund, best thing is to consult previous LP investor that has already invested in the fund, and they expert enough to understand the situation and the actual capability of the HML guy.lot of HML aso these days , got trouble due to mass redemption from investor.

Don't be bashful about asking for something in return.

@Ana Vhan, 1. like @Bill Brandt said you must purchase at least as much as your net sale ($920K) and use all of your proceeds ($520K) in your purchase or purchases. 

Would the proceeds from the perpetual easement be 1031 exchangeable?
