Are there any particular internet options, wireless/cellular, that people are using to manage the smart home features? 

They get 6% of their original investment based on the NOI each year. 

I'm looking at what options I have to pull equity out of other rental properties I have.Does anyone know of investor-friendly lenders that service the San Antonio / South Texas area and will allow home equity loans or HELOCs on rental properties?

Specifically, they use a service like Plastiq; you can pay Plastiq a flat 3% fee (roughly) to make a wire transfer without triggering a cash advancement with the credit card company.

You don't know what a good property is because you are basing it off metrics from a couple of years ago or the one percent rule.

Maybe I am misunderstanding or wrong in some way, but I would definitely reach out to your accountant, or a good one in the area as they can get a full overview of your situation and recommend based off what is required in Missouri. 

Focus on finding a property that fits your family and rental needs.You’ve got a solid base.

The refi loan type is based in part on how you hold the property (in your own name, an LLC, etc) but in general you can expect to refinance out about 75% of the ARV (After Repair Value).

Also, based on my experience there are many areas in the Dallas/Ft.Worth area that make for great rentals.

For example, 200 miles one way (guess) x $0.67 IRS mileage rate x 2 = $268 estimated vehicle cost per round trip, which is per guest stay.I'm using a calculator that factors in management costs (cleaning, hot tub maintenance, CapEX, OTA service fees, supplies, refunds, utilities, landscaping and internet) - it does NOT include marketing/tech tools like Lodgify, Guesty etc. so good flag.
