I ended up selling that particular property.

So whenever the buyer wants to refinance or sell the property my lien comes up aswell and that's when I'm taken care of? 

Used houses in the area sell anywhere from $75-125 a square foot.These are long term rentals that I do not plan to sell.I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

@Andrew Syrios @Jake ThorpeWe now know we can sell that property and make close to the same, if not more at times.

The gurus that sell their courses with the promise that it's easy money.I wish you the best.

We have one other mobile home park and this property will determine my desire to buy more or sell.

Does the LLC that he's offering to sell to you only own the raw land you're interested in? 

Quote from @Andy Sabisch: Will it help you sell more or get more money? 

Well, what would be happening is that your buyer would be buying your house subject to the existing note, since you can't legally sell the property without paying off that note or transferring the debt to the new buyer.

They are based on selling to inexperienced buyers.
