Hey @Jason Panick ,
As a local investor, I've found myself and helped a few friends through the same issue. The question is one of a strategic gamble and the stress you want on you and your family. There are a few options that might be worth considering:
#1. Refinancing / Repositioning
Don't assume that what you have is how it has to stay. There is the possibility that refinancing, or even investing a bit more money into the deal can change its place in your investment strategy.
We had a duplex in scotts valley that we lived in one side, rented the other. We bought it in 2007 and it lost about 1,000 a month (@ my 6.5% loan) if I was to rent both sides. Not the best investment really. But from the perspective of living in it, I was fine since it got me a 3br in a great neighborhood and cost me less monthly than buying a stand alone 3br would have in SV. When it came time to move back to town though, we had a real debate. We were upside down so selling would suck. I could afford to carry the loss, but only if it made sense. We had tried refinancing a few times but were too far under water. Eventually I found a lender who was willing to refinance the property from the perspective of our entire portfolio rather than the property alone. As in, we had enough equity among our 4 rentals that if someone would let us move equity between properties, then LTV worked. We ended up having to bring some money to the closing but the math was excellent (a guaranteed 37% annualized return on the cash). It was an adventure and took a lot of finagling, but the net different was a reduction of mortgage carry cost of over $2,000 / month between the 4 properties. It changed this duplex from the worst performer to the cash cow of our portfolio. Repositioning the cashflow from one property to another fit our investment plan as we wanted to keep the duplex long term, but two of the properties we pulled from were on the schedule to be 1031'ed and this was a great tax free way to put the money to work.
If you have 80k lying around earning 2-5%, you might consider refinancing and using that to buy the loan down (depending on what return that gets you). the math will make it clear if that is a good idea.
You can also look at other rental modalities (vacation rentals etc) that lead to higher cashflows although in honesty, that is basically like taking on another job, and with a new baby in the house, I wouldn't go there.
#2. Wait it out
If you can truly afford the 700 a month without causing any financial risk, then it becomes a question of math. First off is the question of your loan. Is it fixed? at what time horizon. This really affects if you want to wait it out.
The house will cost about 30k to sell (closing fees / 5% realtor fees) excluding holding cost. Assuming your price is 10k under owed value, that is a 40k loss if you try to sell right now. it would take 4.7 years of carry cost to match this loss. If rents go up, then the window is longer. In the mean time though, you are also paying down the mortgage and adding to equity. Depending on where you are at in your amortization schedule & your interest rate, you are probably paying down the principle by 600 - 900 a month right now.
What are the odds the property value will put you positive in 5 years? I'd say reasonably high, but you never know. It is a gamble, but if you have good cash buffers, it isn't a terrible one.
You could also manage it yourself, which if you pick the right tenant is not that bad a chore as PMs take a good chunk.
One other note to consider in the equation is the state of the HOA. Is it well funded. Do they have a history of assessments? Nothing like a bad HOA to really destroy cashflow.
Remember, we aren't talking about whether or not this will turn into an epic investment. It won't. The question is if with 3-7 years of patience, you can turn a potential loss into a gain or recoup. The other key question is compared to what? What opportunity cost does keeping this property result in.
#3 The Swap
Considering the property from the perspective of an investor is one angle. Looking at your personal housing needs is another. A good friend of mine did a shortsale with an upfront purchase. He make enough money / had enough savings that he was able to buy another home while holding this one. In the meantime he listed his previous property for sale. The key was to make sure that his new home closed before a shortsale occurred, and therefor he was able to pick up his new home using his unblemished credit. Perhaps debatable on the ethics, but not absurdly.
#4. Short Sale
It sucks, but you will survive. Lots of americans have. =)
Come to the next Santa Cruz meetup and we can swap stories and brainstorm other ideas.
