Quote from @Zara Massoud: Hi, The PM company we signed on has a clause to add them as 'additional insured'.

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.

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).

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'm not factoring this in right now, going based on the numbers I see.Definitely able to put down additional funds to be creative with a lender, at the numbers you are thinking. 

But this comes with pockets of C/D neighborhoods, and higher potential for headaches;  in addition, appreciation in these zips has probably maxed out for a while.

Most likely you will need to factor this into your purchase price when making offers.Thanks.

In addition, I've helped many other investors finance their deals as a mortgage broker.I'm happy to share my experience as both an investor and lender.
