Now I understand after 4 houses it gets difficult so I was planning to take the income of these 4 houses to finance my Jumbo loan which I would use to buy more rentals which will be able to produce pure profit.

Also you mention the other units will bring in 3k pure profit.  

End of the day without the benefit of hindsight investing is about process and odds and in my opinion its not the right thought process  and pure odds (meaning if you had enough observations and did it all over the place) would lead to bad outcomes. 

By the time you finish your review and inspections of 50 houses - you will have a thorough understanding of the market values - you will be smarter than most agents in the area - you will not be fooled by agents or sellers - you will be in full control.When you are ready to make an offer - you will know that you are making that offer with the pure intent of creating equity or cash flow.All you need do now is to learn how to Control and Roll - using the auction marketing system to liquidate the properties you control.Be patient, take your time - don't let anyone push you into making an offer.The 50 HOUSE RULE works - you'll see.

Its easier if you are more of the thought of living in the property long term as opposed to trying to make it a pure rental in the short term. 

I got my license purely for my investing.

I would like to see a group that meets purely to share information and help each other succeed.

If this goes well, I have the energy (and capital / credit) to do some more purely investment properties.Would love to meet others with similar interests--also looking for recommendations on a good buyer's agent.

We used our savings to buy our first pure rental.

I'll be studying 2 years in Phili which is exactly the time it takes for a tax free saving on a main home, partnering up with someone as a pure investment play would remove a bit of the juice from such a play am afraid.
