The lender I typically work with and send a lot of my clients to is able to do multiple 10% down homes in the same market, given of course that you can keep qualifying for them without going over DTI level.Not all lenders are going to offer this for your area though remember, always best to shop around and find the best deals.

Unless the downpayment amount is a factor, or unless you are adamant on staying in one of the units, you may want to shop around with some hard/private money lenders as well.

Shop around for a broker that will let you if you’re hitting a wall with your current - brokerages have different thresholds for “risk”, different minimum loan amounts, strategies they offer/specialize in.

When discussing the possibility of a DSCR loan with clients who have been shopping around, I often find that when I bring up the pre-payment penalty it is the first time they have heard about it. 

I would get a 500k conventional loan and make up the remainder for 220k with a private party.
