You definitely don't want to get in trouble with fair housing.As for your second question about the applicants who don't qualify based on income, as soon as they hand you the application and you see that they don't qualify, you should explain that to them. 

A borrower's CLADD Scores will determine what loan programs they can qualify for and you'll begin to hear this used more and more in the industryCreditLiabilitiesAssetsDown payment Debt ratios

Probably not, there may be fees associated with this if you take out a loan with this as collateral, normally you should be able to qualify for a conventional mortgage based off of your income. 

I'd be curious what kind of agent wants to jeopardize their standing with their board for this "easy money" when the fees are nominal.

Probably will want you to have "Skin In The Game" - i.e. the lot or land you'll acquire would be used as collateral.Good Luck!  

From NARPM you will get a better qualified, professional PM that will keep you out of trouble.

With down payment assistance, you could qualify today.

But whether or not the property qualifies is another question (as well as your personal financials). 

This is pricing anyone with an average LV household income ($58k) out of buying at the “entry level” now ($58k x 5 = $280k = max qualify ). 

This will avoid needing to foreign qualify your out-of-state entity in the State you are buying the property in.However I am wondering, if I am forming an LLC, with the sole purpose of buying tax liens (I am a foreign national btw), and I don't wish to limit my tax liens acquisition in just 1 State, but instead buy tax liens all over the US..Do i need to foreign qualify my LLC in EVERY State I buy these liens in?
