Not to worry, most brokers require it anyways for you to hang your license... but becoming a Realtor is pretty costly if you arent active and producing.

I have run the numbers on the house and if I can get it at the right price and make the appropriate improvements (new roof, new kitchen, add second bath) it will produce a nice profit.

The story might be different if you are a top producer doing 100 transactions a year for your broker and they are making considerable amounts of money off you.

If you are an agent, title attorney or lender you are probably aware of the new closing situation that is due to take effect in October, but if you are not one of those maybe you are not aware.  Come October "closings...

Each state is different in this procedure so you'll need to check with your state, but in a best case scenario it'll take you years.You can also work with a real estate attorney to either force the heirs to grant an easement or get a lot split proportionate to each property needing ingress/egress and through the process create an easement for such.To find the original developer go to the governmental agency building or planning department having jurisdiction over the property and ask to see the historical files for the subject home and the parcel/lot approvals for the remaining lots in the development.

Making a profit means your property is producing cash(cash flow).  

I know everyone will have something different, but I'm currently a W2 employee paying high tax and am trying to determine what I need to produce on a monthly/annual basis to invest full time.

I will be living in 1 unit, and the remaining 1-3 units will be rented to produce income.

However I can only produce about 20k on paper.  

My end goal is 5-10 buy and holds that I own outright that will be producing a cashflow of $5,000.
