My monthly rents are $6385/month and I have a $260k balance on the 15 year mortgage after refinancing a few years ago and making add'l principal payments along the way.

This will raise our payment up $700 from what it is now but after refinancing we'd be back down to below our current payment.However I was thinking, would we be better to invest even $60k of the $100k into another rental property and use those returns to pay the difference in payment that we’re seeing plus a little extra.

@Alfredo David  What will you save by refinancing your current home vs getting a new mortgage for the rental? 

After refinancing and paying off the owner financed loan and rehab loan, I plan to have enough liquid capital to move onto the next project, along with having equity into the property.

Currently refinancing into a 30-year fixed.

The concern is: Do you have the income/cash flow to support the refinanced payment. 

After construction is complete  refinancing and house hacking two of the now four bedrooms on Airbnb to offset the cost of the raise in the mortgage.

I recently bought a property and I’m thinking of turning it into a rental property and refinancing and pulling some money from equity as a down payment on another property.

I have thought about refinancing to cash out and invest in other properties, but another investor I know recommended that I get a LOC on the equity, while keeping my first mortgage.If I can get this, it seems attractive- I could take out the money when I needed it and put the money back into the property when I don't (to avoid additional interest payments).

We just refinanced a property with a HELOC and at closing with title agency/attorney, the lien positions are simply restated on a document and signed on the new loan with the existing HELOC.
