We're finding houses for buyer not buyers for houses" finding buyers first eliminates most of the guess work and you can hear your property search toward what your buyers actually want rather than tying a property up under a contract and then finding a seller that may or may not be interested in your deal cuz it may or may not be apart of their criteria.Sorry for the overly winded comment.

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.
