If you have $15K in student loan debt and are paying it off little by little (your words)-what are the interest rates, how long will it take you to pay it off, does it affect your ability to borrow for a mortgages (or save the down payment)? 

My husband, a veteran, qualifies for a VA loan, but we're unsure if we should use it for an investment property.

There are a lot of variables involved so its hard to see unless you run the numbers especially since you might replace this home with 2-4 units and where the loans on those new properties would be at a higher rate.

Can we have a USDA loan on an investment property?

DSCR loans are great for that!

Do you see anyone given an auto loan, mortgage, boat, without confirming financial viability to perform on the conveyed financial burden? 

I own a home and would like to brrrr it,  but i need advice on structuring the loan. 

@Michael Kaminski    There is no way around the requirement to move in within 60 days for a conventional loan and call it a primary residence to get the best rates. 

A quick Internet search of "Costa Rica Mortgage Loans" turned up a couple of brokers and private equity offerings.You could also try to get the seller to finance part of the purchase price.Or borrow it from your 401K, if you have one.Depending on your credit score, it might also be worth looking at rates from a local credit union, bank, or even Prosper or Lending Club for a personal loan rather than a real-estate secured loan.

Now I am looking to just get a conventional loan then do a cash out refinance to pay of heloc later.
