Hi Tony,Have you gotten estimates from other title company?

A national auction house estimates $700k, and a local agent estimates $600k. 

In this example, the borrower estimated the ARV between $270k to $300k.

If I'm trying to determine how much to rent an LTR for I'll also use Zillow to see what others are asking for similar homes and how many people have reached out & applied.If I'm trying to determine how much to rent an STR for I'll use the enemy method, AirDNA, and estimates from property management companies.

The $550 was a good faith estimate based off of quotes I inquired from cleaning services in the area.

I can sometimes go higher...but if I know 75% then I at least have a pretty close approximation of what I can get on both lending steps of the BRRRR Method.Now, what lender to use?  

I wrote out the estimates/invoices based off of work that I had done with PM's contractors.
