You buy the property and you have to live with the existing leases in place.Look at the leases and verify the rents are current.See if you can talk with the tenants to see what problems they have with their unit and what their plans are.

I would have a talk with them.3.

Rather than go to a law firm, does anyone have experience utilizing Angel List or similar platforms for legal documents, fund management, etc?

Reach out if you ever want to talk real estate.

There are cheaper one’s in D/F areas but I would be careful as those can create a laundry list of additional issues.

I've been going through "The Multifamily Millionaire:  Volume 2" and in Chapter 13, they talk about property management ranging from 4-6%, on top of on site management that is on the owner's payroll, separate from property management, and that you should budget about 1 staff member for every 40 units.If you (the owner) are already paying a property management firm, why do you have to have on-site management separate from the PM? 

Just want a general itemized list of potential costs to look into, such as cost to develop land, build foundation, permits, delivery and building of modular, hooking up utilities, etc.Thanks in advance!

Talk to your realtor, but I wouldn't think you dont have to say anything. 

Give them a call and talk about what you need.

yes, you can put in time of lieu of money but if you do that, your list will be smaller.
