Quote from @Daron Williams: I just invested in a tax deed here in texas it was a beautiful lot right on lake sam rayburn. i have it on the market for sale the only problem is you have to have two lots to build on.. i found the person that owns the lot to the right of me and there willing to possibly sale there lot the only problem is i dont have the money or the credit  to purchase it.

Yes, your rate will change but not much if you have good credit it will go up around 5.875% to 6%.

It will likely still continue being a difficulty.You mentioned bills, are they credit card bills?
