Looking for first Multi, what would you do in this scenario?

[Matt Crow]

We currently have 4 single families, one with a mortgage and 3 clear but we're closing a HELOC on one of those this week so we can expand.

We want a multi family, but the HELOC won't allow a 100% purchase. My concern is how many mortgages is too many? We have our primary residence, one of the investment properties, and now a second investment property. Would adding a 4th first position be an issue to a bank?

Where should we start is I guess what I'm really asking!!! Thanks!
