One scenario would be buying and rehabbing the property with cash, and then doing a cash-out refinance to recoup the capital, versus buying the house with financing and then doing a subsequent refi.

One option might be to go the hard money route or some form of line of credit and then refinance out of it. 

My job was to bring in new business which meant existing customers seeking to refinance their mortgage loan would not count towards my target numbers.

For example, if you are doing a BRRRR (Buy Rehab Rent Refinance Repeat), then taking an extra month to complete means that you lose 1 months rent which might be another $1200!

You can do a rate term refinance out of the land contract into a conventional mortgage, FHA, or possibly others.

I would like to get some input from some of you experienced BP real estate investors whether I should:A) refinance 2 of the 4 rentals with a mtg for a 15 yr at 3% (currently 30 yr mtg at 4.375% - 4.875%) and let the tenants pay off the mortgage in a shorter term and take my time to pay off the other 2 with lower mtg balance.B) to sell a couple of them at current seller's market and pay off at least 2 of the mortgages with higher mtg balance which would save in tremendous amount of interest and take the extra cash flow to pay more into principal of the other 2 mtg to get it paid off quicker.C) Or to refinance the 2-3 properties for 15 year mtg and sell the other 1-2 properties and invest the proceeds in the stock or cryptocurrency market and try to pay off the mortgages in the future with the gains.  

Coming to commercial lending, can I do refinance as normal property or getting approved for commercial lending is difficult?

How does the refinance in BRRRR work if you own 100% equity in a property? 

I'm mostly just wanting to know where to start, and specifically interested in finding the deals (Buy) and not as worried about the Rehab, Rent, Refinance, Repeat part as those steps make sense to me.

Either way you’ll more than likely have to wait 6 months to refinance for the equity.
