Highly transparent and under-leveraged, the New York real estate market is one of the most stable in the world. If you are looking to make a savvy investment, now is a great time to beat rising property values — which are expected to increase by as much as 20 percent over the next three years — to secure real estate that will generate returns for years to come.

Traditionally, investors looked for opportunities in the affluent suburbs of Long Island and New Jersey, but growth in those areas has become stagnate. But today, we look to Queens, Brooklyn, Bronx, and Hudson County, which are areas that are growing rapidly thanks to new job opportunities, especially in healthcare.

Healthcare jobs are growing by five percent per year — twice as fast as finance, the region’s primary economic and population driver — and account for 84 percent of New York City’s total population growth between 2015 and 2016. The rapid growth has increased New York’s population to a record high of 8,550,405 and shows no signs of slowing.

Here are the five most promising investment opportunities in the New York real estate sector to keep up with growth and changing demographics.

1. Apartment Buildings

As high home prices continue to rise and the city’s population continues to grow, a majority of New York residents are being driven into apartment building rentals located in Manhattan, Queens, Brooklyn, the Bronx, and Hudson County. Therefore, apartment buildings purchased at the right price today can be a very lucrative investment.

Moreover, high proportions of immigrants — 40 percent in Hudson County and Brooklyn and 50 percent in Queens — create a large spread of incomes that create all kinds of opportunities for purchasing apartment buildings that cater to different income brackets.

2. Single-family Homes to be converted into Multiple Units

Because home prices are high compared to rents, pure single-family rentals are not likely to be lucrative investments, unless you’re looking to invest in a special area or are driven by other special circumstances. However, the high home prices that are driving people into renting can be lucrative if you’re able to purchase and refashion a single-family home into one featuring multiple units.

3. Retail Stores

Recent population increases in Brooklyn, and especially in Queens, have not been matched by the availability of new stores. In addition, the Bronx is underserved by new stores. Because healthcare jobs are growing and generating lower-, middle-, and higher-tier income across the city, retail stores are a reasonably safe investment.

4. Office Buildings

The same healthcare sector growth that is creating a need for new apartment buildings and stores, is also generating the need for new office space. Although millions of square feet of new office space are already under construction in Queens and Brooklyn, there is presently no indication that demand in those boroughs will slow even as the new planned office towers take shape. In fact, the office booms in these boroughs signal a healthy long-term future for New York’s overall economy.

Office space in Manhattan may also be a good investment, as Manhattan is still the center of the New York office world. Although 20 million additional square feet of office space are being constructed in Manhattan and are expected to be available by 2021, the number of new offices is insufficient to meet the demand from a booming economy. Nevertheless, reports have not accounted for additional space that is to be provided by new World Trade Center Towers, and the future absorption rate for new office space is unclear.

5. Mortgages and Construction Loans

Rising home prices will keep equity rising, too, making mortgages a sound investment. Although there is always some risk of default, that risk is just about average right now because rising home prices are in balance with incomes.

Alternatively, but in the same vein, construction loans will also go up with only an average risk of default, making them another prudent investment. Ingo Winzer, contributor to Forbes and president of Local Market Monitor — which has followed real estate dynamics since 1989 in over 300 communities — predicts 45,000 new houses and 70,000 apartments will be constructed in Queens over the next three years. Brooklyn will only see 40,000 new homes constructed, but 110,000 new apartments. The Bronx will likely experience modest new home construction but is expected to grow by 60,000 new apartments.

The idea that New York real estate is out-of-reach for those looking for sound investments may be closer to reach than many would think. The worst thing to do when thinking of buying real estate is to wait — especially in the ever-booming New York City.
