I figured I could earn a money market return on the cash during that time and offset some a large rehab I have going on. 

As for the returns, you need to look at the hold period.

And you don’t want to pay them off because that decreases your return of equity.

This will then be a schedule E entry on your personal income tax return.

When cap rates return to historical norms, values will drop unless net operating income increases.

We begun our search for multifamily and even got preapproved for a conventional mortgage loan in the 500s with 20% down, but as we continue to evaluate many of these properties and their cash flow, it seems like a high cost of entry, ownership with a low return/cash flow.

The real question is whether paying off a loan at 4.3% is better than investing in something else that may get xx%Most people shoot for their rentals to have a CoC return of 10-15%.

In order to get positive cash flow, I'd have to stretch the rent amount just to break even.Another financing option would be to re-fi the condo again, basically re-finance remaining $66,000 amount with 20% down @ 5% on a 30-yr fixed:Rent Summary: I'd have to re-fi & put 20% down in order to have good CoC return (down payment + improvements + agent fee + closing costs), as well as a positive, somewhat plausible cash flow.

Imagine a world where someone hands you 100k and says “Find a way to grow your business and return this money to me one day”......How would you grow your business / net worth/ cashflow the fastest way possible??

@George MoehlenhoffIt is really hard to say whether or not it's a good deal without all the facts and looking at your tax return.Are you filing one state tax return?
