We're eager to get it rented out as soon as possible and would appreciate any recommendations for reputable property management companies in the area.Thank you in advance for your help!

I'd recommend talking to a mortgage broker who is licensed in your state. 

I have already met some very knwoledgeable and experienced investors and operators through BP, and was hoping to grow that list.Thanks ahead of time.

I'm wondering what is the current average cost, and seeking recommendations/advice.Ty 

Does anyone recommend books, courses, or anything to help me learn the general terms and what it takes to become a private lender/broker?

I recommend starting with the New York City Department of Finance: https://a836-acris.nyc.gov/DS/DocumentSearch/Index.Select the district you are interested in investing in, and then search for homeowners in that area.Best regards,Peter---

Any other recommendations?

For ease and simplicity, I would recommend having one of your friends/stable renters to rent the whole house.
