New York partner

[Vincent Wright-Mensah]

Hi BP  fellows,  I have a gentleman who has agreed for me to  hold a note on his $1,000,000.00 single family residence in westchester county NY. The property can be rented out for at least $8000.00  a month.  However my problem is that I'm new to this and the owner wants to see some financials or track record for him to go ahead which I don't have.  I lost two similar deals  already. Any help/ suggestions   out there is most welcome.
