I'm sure you are already working with a realtor who specializes in multis in your area, if not that would be a good first step!

Always looking for a great deal, partners, lending options, and how I can help you as a realtor.

I know we can get some market research like state-wise from the Realtors association (like this one https://www.njrealtor.com/research/), but if I want to go deeper and understand the market in a county or even in a specific city, where should I go?

Realtor wise, only know of one.

So my realtor found a property for me. this property is listed on the MLS for 75k....She contacted the listing agent and submitted an offer for 76k in cash.

Thanks for all your kind response.To sum up, we were ripped off by our realtor/contractor. 

Went through a couple realtors before finding the one, and a few lenders wouldn't lend to me because I am out of State and they all said out of State has the highest default on loans rate, but I kept trying and looking and found a great guy who took care of me as well as recommended me to my property manager who put a tenant in place within a month of ownership and keep in touch with me on a weekly basis.

Your next step would be to contact a local lender to make sure the numbers will work for you...You also want to get in contact with a local realtor or investor to find out what market rents are at...

We gained $75k after closing and realtors.

Having her mine the MLS for me for deals that fall outside of his typical Realtor activities/targets/inventory and which fall into my wholesale/investor wheelhouse.That said, what specific deals are most appropriately located inside of the MLS and which investors and/or wholesalers would appreciate getting their hands on?
