I was fortunate enough to attain an internship for school with a company called LandStay in Scottsdale, AZ who specializes in wholesale land. 

Biggest individual expense being food as I have a special diet due to my Chron's and Celiac.Everything left over goes towards paying down debt.

Find a local lender that specializes in dealing with first time homebuyer clients in general.

You're best bet is to start networking with attorneys that specialize in probate. :)
