Hey @Ken F.,
I think that is a great question and honestly a great problem to have. I think you have plenty of options. Even if you are not cash flowing right now, you have a newly constructed home. This tells me the maintenance on the property will be minimal over the next 15 years. Most people acquire older homes, brag about there cash flow of $300 per month but spend over $2,000 a year on maintenance. You already have equity, appreciation still looks great in that area, and you should be raising rents every year. Being asset rich and not cash rich is not a problem when looking at the future. On the other hand, if you feel confident in finding another home that will cash flow over $300/month then that is great as well. If that is the case, I would sell and roll on. Lastly, get creative. Advertise the house as owner finance. Have the buyer put 20% down and charge them a higher interest than you pay a monthly in PITI. This frees up your capital, cash flows the property, because you don't have to worry about repairs or vacancy. Call up a lawyer that can help with owner finance (wrap) dispositions. He/She will put your mind at ease because there are a lot of uneducated people out there that will talk you out of this strategy. You are definitely in a great position! Good luck.
