Most of my renters choose #1 because it provides a clean break.I document everything and I don't accept the early termination notice or start the clock until they pay the termination fee. 

And who is verifying information with tax records and the seller, securing disclosure documents, and entering the property into MLS and any showing applications?

When selling for sale by owner (FSBO), ensure all legal documentation is in order and consider consulting with a real estate professional or attorney to handle the lease transfer and legal aspects effectively.

Hopefully, you've approved a bid they submitted, so the cost is fixed - unless they can document the need for acceptable change orders.If they are charging hourly, then, yes, they may be able to charge you more the longer it takes.Keep in mind, your PMC is unlikely to have an exterminator and other licensed contractors on staff.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Document every incident and move on.

Again, have to be self employed to do this AND rates are higher on these loans.You will be able to add back your paper losses on your rental business by your lender using this form (if they are competent which not all when it comes to investment real estate) :  https://content.enactmi.com/documents/calculators/Form1038.C... 

Obviously, I am going to be very, very diligent about getting all the documents necessary and looking over the area as we get farther into the process. 

Banks like to match short term assets with short term liabilities, and vice versa.I don't believe that DSCR loans are "expensive", but they do require a more thorough underwriting and higher amount of financial documentation other private and hard money loans.It generally helps to have a Fractional CFO or Loan Consultant (not a broker) that will work on your behalf to negotiate better DSCR terms and rates.

Is there any document within the BP website?
