I've tried many other personal finance tools and consistently had problems staying connected, so they're the exception.

@Shuvrajit Mukherjee agents already have tools that do a lot of that like Remine or Realist.

Not a right or wrong answer based on your investment horizon but a good tool to use.

If there issues that need to be worked out with the 6-unit property, I would utilize that as a negotiating tool to work out a seller financing strategy with the current owner. 

This is an essential tool for anyone buying a tenant-occupied property. 

BRRRRs are a useful tool for the right scenario, but it sounds like you have the opportunity to buy a house with basically no cash in, and with probably some of the cheapest financing available.

DSCR loans definitely seem like a good tool for scaling, especially with strategies like BRRRR where cash flow is critical since it doesn’t rely on personal income or DTI, making it easier to qualify while keeping cash flow positive.

Seller financing is just one tool of many in how to finance a deal.

As for the refi side, DSCRs are an excellent tool to utilize as they are based off the property, not you as the borrower, so no DTI hits / personal income verification required.
