A mortgage lender can help determine if refinancing or tapping into equity might allow you to acquire additional properties.Consider a 1031 Exchange: If you're open to selling a current property, a 1031 exchange can defer capital gains taxes while enabling you to upgrade to a larger or more profitable asset.

We also refinanced 1 rental and went from a 5.75% to a 3% interest rate, changing my cash flow over $200 a month. 

Tax-deferred strategies like 1031 exchanges and refinancing allow further tax-efficient wealth building.This post does not create a CPA-Client relationship.

My goal of refinancing was simply lowering our monthly spending to reallocate towards future investments.

And because I'm looking for a long term finance situation, I'm not looking for a loan that is going to have a really high interest rate, with hopes of refinancing later.

For your refinancing needs, there are definitely lenders out there who specialize in DSCR loans for investors.

were these all BRRRRs that were purchased with cash or short term debt and then refinanced? 

If you decide you need to hold the property it makes refinancing either impossible or expensive. 

It's highly doubtful, you prob won't find a fully refinanced deal on the MLS or through realtors. 

Reserves: Do you have enough cash reserves to handle unexpected costs or delays in refinancing?
