If you want stability in any market environment, stick to B & C. Amateurs often look for Class A, shiny new buildings that look pretty. But during economic downturns, Class B & C experience very little volatility in market values and market rents. Let me explain.
For ex. the decline in oil prices and resultant job losses in the Houston market caused many Class A tenants to downgrade to Class B, maybe even C. The rents for my partners Class B & C assets remained steady. And they own many 300+ unit buildings, lot's of them. They reported no change or drop in rents, but an actually uptick in occupancy levels and a large waiting list for tenants looking to move in. The Texas market also saw lot of new construction, many of them have lost some value and have had to lower rents and offer more concessions.
As an investor, you will always find value-add opportunities in Class, B, C and even D. I know it sounds bad when one thinks about class C & D, but it works. A article recently published in Biz Journal about a friend of a friend who purchased a 160 unit Class D- with $65k/month in rents brought it up to $90k/month. Fact is, most investors get discouraged when they tour Class C & D properties. They see the type of asset it is, the type of people that live in them and the overall condition and get discouraged. Most wannabe investors want to see granite counter tops, wooden flooring and nice appliances, all with a discount so they can get a good deal! That's impossible. Not going to happen. I brought many crappy buildings in MA to compete and I'm not going to sell that to you at a discount. You will find value in buildings that are kind of falling apart cosmetically or maybe even boarded up. Sure, location is critical, but the condition of the property is even more important. I know what I'm saying is counter intuitive. My partners own 1,400 units and they executed the same strategy. I use the same strategy as well. I just posted in the success story yesterday about one of my properties. Look at the before pictures. It looks bleak, but I see value.
So my take, focus on Class B & C for stability without having to worry about the impact the next recession will have on your properties and rent collections.
