I would have a house already but that is used as rental and I bought it using private lenders.

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. 

to simplify, here's what i would do: don't borrow private money, or partner, until you have a track record. 

Many times a lender buys a property back at a sheriff's sale/auction where they are selling properties as part of a foreclosure.

Ideally was thinking a duplex, triplex, or quadplex to get started and use an FHA loan but I also have a private lender that can possibly help with up to $200k worth of a down payment.

I spoke with 10 lenders.

My name is Christin Milton and I am a Private Money Lender.
