In order to make a sensible decision with regard to the future potential of keeping a Harmon Cove unit as an investment once you no longer wish to reside there depends on the purchase price for which you can obtain the unit and how much of that price you would be mortgaging. Adding up your Principal, Interest, Taxes and Maintenance and then comparing that total to what the unit could be rented for would determine whehter you at least have a break even situation or possibly one that nets you a return . Remember that right now the market is quite a bit lower than the future potential for values, after having gone through a downward spiral,and it is likely that in addition to having a future tenant eventually pay your mortgage , you likely would realize equity in the place when you did, in fact, choose to sell it. You could watch the market closely, and since at that point, it would no longer be your primary residence, you could strategize the best time to sell when that time comes.
In the meantime, you will be living in a home of your own, you will stop paying for someone else's mortgage, and you will feel more comfortable about doing improvements to the property that suit your needs and tastes, because at that point, it is your safe haven and the place you call home.
Interest rates are good, prices are just now again starting to escalate (so you still have time to get in before it spirals again) and if you like Harmon Cove and the area, then you already are one step ahead of the game.
Let me know if I can be of assistance in any way.
