I have found broker who will relay me borrowers' information, so I only need to find someone to borrow for low interest rate from.Any help will be much appreciated!

However, if your current interest rate is low, be aware you will be buying into a deal with much higher interest rate with today's rate.For your new purchase, you should be able to use a DSCR loan and get financing without income as long as credit is good.

This would also allow me to keep my primary at a low rate loan. 

The only people who succeed at birddogging are the ones who learn everything they can and know it's going to be a low-paid slog so they do the work hard and one day it changes because you have earned more.

Why pay off a low rate interest.

Look for properties with low taxes, separate utilities, strong demand, and potential for rent increases.

The net result is basically the same, but it keeps the two properties separate from a lenders perspective.Any low down payment money, particularly on an investment property, is going to come from a private money lender.  

In multifamily here in Reno, NV (just over the hill), we have seen some great deals with higher cap rates for buyers, but also very low cap rates on some renovated, turn key inventory. 

They are inexpensive, they usually come with mineral rights (big plus in Texas), they typically have short redemption periods, low rehab costs, and sell quickly at the right price; they also have large ROI.
