I’m considering refinancing with a DSCR loan, which could lower my rate into the mid to high 5% range.

At $750K, you're in range if projected end values support it.

It's a user-friendly platform that offers a wide range of features tailored to the needs of the real estate industry.

So it sounds like there is indeed a market for such a product, if it actually delivered what it promised: A perpetually up-to-date database of all STR related regulations for every municipality nation-wide, with a filterable map-like interface. 

As others have expressed, so long as none of the deal metrics change from quote to closing, the rate should not change.

Quote from @Marcus Welson: I am looking to purchase a property in the $330-$340k range. 

The size of the lots range anywhere 1.5 acres to 3 acres.  

Minimum total price for a smaller, yet still “efficient” property would be in the $1,500,000 + range in the less expensive states.

Their content is comprehensive, beginner-friendly, and widely trusted in the investing community no paid upsells needed.

(I'm in the mid 550 range, not much debt but only 1 income and 30k in debt)2.
