I just refinanced a triplex for a client and his loan payment is 2k and he collects 4200/month between all the units. 

You could explore options such as refinancing to release equity while keeping a manageable rate, especially if you need capital for the future multi-residential development.

Contractors all the time either fail to finish or finish in a way that prohibits you in selling and exiting or refinancing at the number you expected and now you have to leave way more in than you thought. 

Can I secure the same loan for both scenarios—buying a new house from a contractor or refinancing in the BRRRR method?

The current mortgage rate is 4.375% and I want to avoid refinancing if possible. 

Given that your rental property currently cash flows over $3K/month, the DSCR might be too low to qualify for the full $900K loan, unless you can show additional rental income or strong reserves.If your goal is to access that $200K for another investment, refinancing with a DSCR loan could be worth losing the low 2.99% rate, especially since it would eliminate the high-interest HELOC.

One route is to explore refinancing these properties into your name with a cash-out refinance, which would allow you to access some of the equity while officially transferring the deeds.

Portfolio Refinancing: As properties appreciate, consider refinancing to free up capital for new projects.

, built equity and refinanced when rates came down.  

It might be a bit risky as a first-time investor, so I’d recommend this option only if you have a clear exit strategy, like refinancing or selling the property within a year.4.
