This community has been so helpful in helping me grow my portfolio.

Also remember that we are getting to the slow months to lease up properties and it may take a while.

I would try to network with other MTR landlords in the area to determine best course of action  Yea, I would agree that the rate wouldn't be on par as an MTR that is furnished, however I do remember from my renter days that the shorter duration leases were more expensive per month than the yearly leases. 

Remember, you are the conduit to the deal.

The larger your portfolio grows, the better systems are. 

As @Chris Seveney mentioned there is not really enough equity in house 3 to get a meaningful LOC. even if you were able to leverage enough to pay off House 2 the new rate you would be paying would be higher than the existing mortgage, so you would still be behind overall.Your ROI on those payoffs vs keeping money in index funds is not very good either.Lastly, remember that cash flow from rentals can seem good until it’s not.

Remember when I said all it requires is to not get greedy; some would see this and obsess on being at "only" 40% ownership now and completely ignore the fact of how all that math plays out in this. 

I only ask because I work with a few different builders that have 2-4 units in growing markets.

Have a system in place already if you ever grow bigger or expand, don't have to change it later or figure it out later.
