I'm sure that once I feel more secure in my knowledge in real estate investing I will probably use other methods in order to obtain those rentals.  

I haven't talked to any refinace companys yet, looking to get eductioned on how and the best method to go about this,  Thank you 

Not sure how to answer this when applying my partnership methods to your situation, without taking up two pages or more.  

Borrow from two hard money lenders to pay cash Please advise us in the most astute method of action.

Doing the latter would improve my cashflow from that paid for unit from 1000/month (for the paid for house left as is and cashflowing) to about 1250-1400/month of cashflow with the cashout refi used to leverage 3 more properties.I intuitively understand that the refi method will in the end make more money, since I'll have increased my house numbers by 3 (from 3 to 6), adds ~450K to my portfolio in house values (each being roughly 150k) and will have renters paying down the mortgages and also covering taxes and insurance as well.  

I have a great credit score with about 7% debt to credit ratio but picking the proper finance method to acquire properties keeps me from pulling the preverbial trigger :(

We will explore those ideas. 

I came across a video where a lady broke down how to pay down a mortgage using  HELOC her method seems doable not sure if I can post the video here if I can let me know  and I will share it..My question Is it worth doing this with a rental property ?

Are there any pros/cons to this method ?

I believe it is a tight for deals to flip on the MLS right now and more creative methods are working better.
