Michael P, "Ragged Dick" was the first of a series of books written in the 19th century in the USA by a man named Horatio Alger. They featured an attractive street urchin shoe shine boy, "Ragged Dick", who decided to work hard, save his money, who pulled himself up by his bootstraps to become a highly successful businessman. They were sort of morality tales for young boys, to encourage them to work hard and save, and that by doing this they would become rich important business leaders some day. I don't know how realistic it was back then, but they were very popular, and made their author a ton of money. Sort of like the author of Rich Dad Poor Dad!
OP, Joe Splitrock is right. You're in luck. Everyone and his brother wants to buy multifamily units now. So you should be able to sell them easily. So many people are paying to take classes on learning smoke and mirror concepts (many of which I'm seeing people echo in these comments) about how to refinance or consolidate and pay down mortgages to yield positive cash flow, or that you're just not managing these likely Class C multis right from a thousand miles away. "Make a trip out there and get it all straightened out!" (For another several thousand dollars in flights, hotels, and car rental on a complex that's not producing, change the management to another charlatan property management firm, and nothing changes except you're out a few thousand dollars and some vacation days from your real job.) It's all total BS. Say you have a property that's worth 500K, that you are into for 100K with a 400K mortgage. It's not "cash flowing"; in fact, it's losing money. So you put in another 100K to pay down the mortgage. Now it's neutral - neither losing nor "cash flowing". So you put in another 100K, and now it only has a 200K mortgage. Voila! It now "cash flows", although very little. But it cash flows! Success! You're into the property for 300K, and it's making you a pittance a year. But that's okay, it cash flows, and someone else is paying your mortgage! Success! In 30 years you will own that building outright! And it is costing you nothing!
BS. It's costing you the 300K in capitol that you're into it, that's producing almost nothing. If you had bought a three family building near home outright for 300K, that brought in 3000 a month in rent, it would likely have produced 25K/yr in PROFIT, with you managing it yourself. Or if you had bought three buildings like that, each for 100K down with 200K mortgages, and managed them yourself, the three would have brought in 60K/yr in PROFIT, with you managing them yourself. Point is, "cash flow" is a BS concept, smoke and mirrors, that these charlatans running expensive courses teach you. What matters is return on investment, meaning how much money is your money making for you? And of course, we should all buy property in areas which are going to experience high and rapid appreciation, so it doesn't really matter if you aren't making money on your investments, because you chose them so carefully that while they're "cash flowing", they're also going to increase in value! The corollary to that is to be sure to buy your stock investments right before they're going to go up, so that you'll make lots of money! (And there are expensive courses to teach you how to do that as a day trader in stocks with your own money, too, that are worth just as much as these real estate investment courses.) Idiot schnooks like us know how to time a real estate market about as well as we know how to time the stock market - meaning, not at all!
Take advantage of the fact that the bottom hasn't yet fallen out of this "Florida land rush" current fascination with multifamilies and apartment complexes, and SELL them! Then look into investing in real estate very, very close to home, that you can manage yourself while still holding down your day job.
