As I don't have large down payment, I am thinking to start building a portfolio with finding off market deals that have equity and do bit rehab/renovate and later get refinanace to pay off HML with a traditional lender/DSCR loan. please share any thoughts on my plan and any lending resources.

And get a meeting with them and explain your situation and offer a payment plan..

It definitely boosts cash flow!

any subsidy of your mortgage that results in less net payment then you would pay in rent is still great. 

Another option is to have cash saved for the rehab-- it really depends on your situation and the extent of a renovation.Start hitting up lenders in your area and see what they can share-- each bank might be slightly different.

Excellent deal for the minority partners (zero cash contribution) but a low ROI even accounting for tax savings of $24k/yr on a $500k cash investment.

No, we would be bringing some money to the table for down payment, closing costs, etc.. 

Are you referencing cash on cash return?
