@Zara MassoudAdding your property manager as "additional insured" is standard practice and beneficial for you.

Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

I am considering building up on my fourplex. 2 additional units.

I will say anyone offering this should be giving you all the pros and risks of the flint marketplace.

If you sell a property, and do a 1031 exchange with the proceeds, but don't need all the proceeds for the down payment of the next property, are you taxed on the additional profit that isn't part of the exchange?

My goal is to leverage that equity for additional income.

I have a property I’m looking at in Missouri that’s about 1,400sqft, and not sure the difference between a Cash and a Novation offer. 

They will just wait for you to cancel the contract and offer on the listing themselves. 

I've managed up to 400 rentals and never offered a concession.
