It has 42 efficiency apartments, 160 one bedroom apartments, and 20 two bedroom apartments.

Can my fellow investors help me and tell me what is the best and most efficient way to get started?

@Gaurav Mehta Like all others have mentioned there are cheaper more efficient ways to acquire a Duplex which I agree 100%.

I've read about heat pumps, and that's there's more to electric heat than before so I am not sure if electric heat has improved in cost efficiency?

In my opinion, buying one house, rehabbing it, renting it, refinancing it, and doing it all over again, is not a very efficient way to scale, especially for the amount of risk involved with this strategy.

I personally place speed, efficiency and customer service first.

Any better/more efficient methods to trying to get my foot in the door to get into brokerage?

Gather all documentation you can and take it to a good attorney that specializes in landlord-tenant law for your jurisdiction, someone with a great track record for successful and efficient evictions.

But if you have a contract on a mediocre deal, you are going to have a LOT of frustration and headache trying to get it sold.If you have fewer offers accepted, but they ALL turn into deals, it is much more efficient.
