In the past we've always relied on agents, but this is time consuming and it always feels like we're being a bother when asking.

Were still seeing a healthy amount of investors from up north and foreign nationals purchasing in Florida. 

This negative position can consume years of cash flow to recover.

For healthy investor focused mortgages check in with @Joseph Chiofalo for options and a second look.

It seems to be a healthy mix of the two when it comes to real estate as a business and as an investment.

You answered your question in the last sentence - disclosures are required on conventional but not for DSCR - these are really aimed at overprotecting the consumer (non sophisticated or non real estate professional) - since DSCR Loans are 100% business purpose and for investors (and typically for experienced investors or non-first time buyers only), there is less need to overly disclose / overly explain everything in a disclosure since its assumed they are experienced and know the basics

There is far more prep, detail and care that goes in to doing a decent job and it's super time consuming.
