The brokerage I work at also owns a construction company so would be happy to discuss some estimates.

Sure as hell beats paying $40k to an actor fronting for a real estate marketing company operating out of Las Vegas or Salt Lake City and providing guidance by a failed salesman reading answers from a script.  

What servicing company are you using, and why did you choose them?

Escrow companies that are responsive and communicate well.

I worked with a wholesaler that has a subsidiary lending company. 

You can see big companies moving and developing here like Intel, FB, Honda, Google, Amazon, etc, population growth, and job growth!

HUGE difference...... and how much more $$ will each generate to offset that cost?

I think this is different. 

But there are some differences you need to be aware of compared to multifamily.The lease is the most important part.

I used to run a national mortgage company and had an investment firm in CA working on solely residential property in different locations and the got into multifamily acquisitions starting in 2018.
