They do make hoods specifically for this sort of situation. 

I live in Henderson NV, I've been looking for some sort of deals here but I've been effectively priced out of the market.

The company I have been using does the injection method, its sort of a spot treatment method.

What @Chris Martin said.A real estate/closing attorney, a promissory note and a deed of trust are the primary (sometimes only) ingredients needed or required to close on a property using private or hard money in this state.The going rate around here for a RE attorney to draft or review these docs and close a loan is anywhere from around $400 to upwards of $1,000 depending on who you know, how much business you throw their way, or the direction of the wind that day.The cleanest way to do it, if you're interested in that sort of thing, is for the PML to have their own RE attorney draft the lender docs (Note, DOT, some want a personal guaranty as well) and then use a different RE attorney to close the transaction with.

I only just moved back and my [new] accountant is just sorting that out now.  

The floor was sanded and sort of refinished... this is one of a long laundry list of 1/2 a$$ed things, but I digress.

Work some sort of deal with a MH dealer to place homes on the lots and then we would do all the ground work to get people to come finance them.

Sometimes, that sort of discussion sparks new ideas and help people, not just myself, focus on where they want to devote their time.

What I can do is warranty it this one time but you really need someone to fix the drainage issue... by the way we do that sort of work, my guys will already be here fixing the foundation for you so I can offer you a special price of 1999. 

You can contact him directly and try to work out some sort of deal to get the lien released prior to close, but if he knows you're going to close he has little incentive to cooperate and it sounds like he knows the game better than you do.
