Keeping a sustainable business?

I always thought it would be good to install solar or wind at the tower so it is self sustaining.

The brokerage seems to be growing rapidly;  can this be sustained in the long run with very little brand recognition amongst customers (compared to a Keller Williams, REMAX, Coldwell Banker etc.)? 

I chose STL as it has many working class areas where rents remain at sustainable levels to cash flow.As our first investment, I looked for SFH that required minor repairs to get rent ready.

I agree that the people you deal with have very few options left, and having empathy for their situation is critical for sustained success.

The question is how long that will take and how much loss can you sustain.

Those properties could could sustain a massive hit to value and still deliver him a big chunk of gain simply by holding. 

What does it do, how does it make money, is it profitable and sustainable?

Most markets across the nation have seen climbing prices and it simply can't be sustained forever. 

@Matt Shields in the long run I’m not overly concerned as this corporate entities have huge overheads and as margins get smaller and smaller they will have a tough time sustaining themselves.Small operators who work from home or small “mom and pop” offices will do better as they will be able to live from previous profits as long as they don’t squander the proceeds.If we have even a minor correction in the market, the large corporations could be left sitting on a lot of negative value inventory that will need to be liquidated In order to cover overhead and can only benefit the smaller entities with cash to scoop them up.My 2 cents for what it’s worth.
