Hey Donna,Verify bed/bath count and square footage with the other rental listings that appear, but the median rent should provide a rough estimate of rent per unit.

Provide criteria to any applicants.

But most investors are looking to rent out the property to cover at least these expenses and cash flow on top of this.

Your offer to purchase should include a requirement that the Seller provide all documentation and agree to sign an estoppel certificate (also called an estoppel form or agreement).

This is something I am happy to provide to my clients.

You can also find the link I provided by hovering over the "Tools" tab and clicking "landlord resources" under services.I would recommend doing some research on what company best fits your screening needs. 

It’s zoned as residential top floor apartment and 1st floor commercial/ office overlay.

I also would like a service loan provider or some type of assistance to walk me through the first process, to understand the business and become more comfortable as I continue my note investing.

I also provide a move in sheet the tenant fills out if there are any defects in the house.  

Quote from @Balaji Varadharajan: I provide move-out instructions that spell out my expectations, including a small table of wear-and-tear items.
