You need to build up a massive sales business first so that you can later start those businesses as a way to collect more of the down stream money you've created.

The latter strategy also has tax deferral advantages for other earned income streams.

It would be risky to interrupt your income stream until your wife completes her doctoral program and gains employment. ...as mentioned if you do not have 6 months of saving or more to stay a float until your real estate earnings kick in you will be in a risky predicament @Josiah Richard

Or maybe a single-family with an accessory dwelling on the property that can be rented out.This is referred to as a "house hack".

Depending on the conditions of that particular market, the highest and best use may be to demolish the building and sell the site to a developer.If the highest and best use is to keep the improvements, then you have to consider the durability of the income stream and/or comparable sales. 

Niece is trying to sell at 60k and she states the dwelling will need torned down (her personal opinion) but is not condemned by the city (as far as I know) and is surrounded by 200k large homes.

Im looking for a steady income stream now .

Yes it is a great stream when you put the parents on a weekly subscription for the kids, plus food & drinks, and tournaments.

So lots of benefits like income stream from commissions representing yourself and others, referral fees, mls access, etc.The on the job training and mentoring you get from the broker you choose to hang your license with is also very important for a new agent.

That situation can also create streams and pools under the floor.
