Meet with a local banker & schedule a time to talk with a mortgage broker, they'll give you at least a baseline of what kind of down payment options and rates are out there.After that, if you're still wanting to research more creative options, do some looking into seller financing (a very hot topic with good, and bad, advice out there), look into private lenders, and commercial financing options.If you're wanting to live in 1/4 of your quadplex, then conventional residential loans may in fact be your best option as you can purchase that with a fannie/freddy loan with very low down, and use up to 75% of the income from the property toward your own income. 

:) Would love to make some connections/friends here! 

Congrats in advance on your purchase :)

By purchasing a multi-unit property, living in one unit, and renting out the others, you can cover your mortgage payments and start building equity while gaining rental income.

You can go to bed at night sleeping like a baby even though you charge 4X what others get because you know, you helped fulfill a couples LITERAL life dream.

Seems like too much work for too little return UNLESS you own the property, or perhaps have an option to purchase the property allowing you to capture any increase in value.   

If you provide your credit score, purchase price,  estimated down payment, property type, occupancy type and desired term, then most lenders should be able to provide you with their current interest rate, any associated points or lender credits for the rate provided, and their total origination fees.   

@Mario Morales - As some others have said I think the strategy is sound, but the key would be to find a distressed property that you can drive up the value with renovations so that the new value is 25% higher than the purchase price so you pay back your HELOC.

I currently live in Phoenix, AZ but I'm looking to purchase land and put two prefab homes on it with my business partner.

I purchased the property roughly 5 years ago.
