Have proof on hand (easy enough to find) online of the missed tax payments and any documentation that supports that he specifically didn't pay his taxes.Probably a simply mistake on his part, but now if he wants to develop on it, he either has to land lease it from you or buy it back.I'm not sure how the whole tax deed thing works, so that would be something you have to figure out between the two of you.

If you had not shared your post, as an owner, I would not be aware of the issues you are experiencing. 

But I'd suggest you definitely partner with an experienced investor.

Jeff - Sorry to hear you are experiencing delays in lease up. 

This way the broker can search hundreds of lenders (Including Easy Street Capital) instead of just hoping that one lender can get you a good deal.A direct lender can work very well for Conventional loans, but if you were hoping to get a good deal I would look elsewhere Or you could search for hundreds of lenders here on BP or online yourself and avoid paying broker fees..
