Need more information surrounding why your current lender is suggesting they cannot utilize the rental income on your investment property.

I would suggest Indy.

I suggest having smart TVs and let them log into their own accounts, preferably with a guest mode so they auto-log out after a certain number of days.For catering to families, I would concentrate on providing amenities like puzzles and games. 

simple - treat it like any other real estate closing. you go through attorneys and title companies. 

I’ve even seen a friend in Austin organize a simple field trip to another city..from what I’ve heard that kind of trip can spark interest in fresh markets.

As long as you keep track of everything and report correctly you should be good to go.I'm always in the camp to Keep It Simple Stupid when it comes to running stuff through LLCs until you hit a certain critical mass of assets and/or income.Hope this helps!

What other books does anyone suggest?

I for one built a simple chrome extension to see if the mortgage is less than rent and accordingly provide that information on every zillow listing page.

I would suggest you take a few months and watch the market before jumping in because the market has adjusted the pricing because it's hot. 

I would suggest shopping it around a little more until you find a lender that offers reasonable terms and has a positive reputation.
