Or, search for smaller multifamily buildings on the county assessor/appraiser site.

I don’t want to bother them to get updates, I thought there must be a site where I can find information. 

What are some good sites to find real estate grants if any?

I don't know if you would need anything more complicated than that.

To complicate things 1) he has no vehicle.

You can also find a lot of free info on the web from sites like www.city-data.com.

And then you have an Operations LLC - a shell LLC that is the public facing entity, doing all the interactions with tenants, contractors, leasing, hiring, management, etc. with no assets and very little funds beyond whats required for proper capitalization and operations.That's the basic idea, but things get complicated from there due to the partnership, financing, commingling, etc - which is your current situation.

I just got a loan on a 55k property with 20% down, our income is already very complicated with self employed income, rentals etc.

There are a lot of resources on this site about wholesaling.

If you want convenience with the whole process you can use a site like Cozy.co.
