However, I am in the very early stages of the business plan.

I work in Business Development for a Property Management company over Greater Houston only and am first contact for Owners/Investors looking for management...

Our company is starting out in the asset recovery and wholesaling business in Columbus Georgia.

What’s your recommendation for a dishwasher brand/model that’s likely to last but not super expensive?

Replacing appliances just a cost of doing business.

If you start to acquire many rental properties, you can actually create a business account with Reliant, which will automatically turn electricity on and off, as tenants move-in and out. 

You can maybe save some cash and just get a single line virtual dialer like Vonage Business or Ring Central (look for month to month only), you don't need a massive power dialer right off the bat (another $150-$250 per month). 

Someone with experience with visa holders being passive business owner and investor.

Just out of curiousity why would someone choose this model over a short term rental that is isolated by itself (privacy) or a hotel? 

I am open to the possibility of investing with someone that understands the market and has been in this business already.
