I tried using the biggerpockets rental calculator this morning and the cashflow was negative, but I may have been too conservative with the numbers.

Most lenders require proof of someone else paying the note for around 9-12 months so that the debt isn't counted in their DTI calculation.

Here's a bit more in detail about how rates are calculated for DSCR loans:1.

Research market rents, carefully calculate expenses, and ensure you have a solid lease agreement.

Success in real estate requires courage, perseverance, and the willingness to take calculated risks.Internalize these principles and apply them in your real estate endeavors, and you will be on your path to success.

I've calculated the lump sum costs to be $9,500 for buy and sell combined and a monthly reduction in cashflow of $347 due to the new loan and taxes.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

A Title Company can distribute the proceeds based on the agreement, and consulting a CPA will help calculate tax liabilities and explore strategies like a 1031 exchange to minimize taxes.

The calculator estimates that operating expenses are equal to 50% of the monthly income.  50% is a rough guide. 

If that is the case then that is considered cost of doing business and I would advise that should be calculated in your costs/returns you provide to the investor.IF you are referring to the investor who is the borrower - then I would have included that cost in the loan agreement.
