That usually only applies if you will be bringing customers to your home.

I think you've really highlighted the difference between you and I, and that is that you appear to consider America a market, while I see it as thousands of individual markets.

I have customers come into my business and pay by credit card.  

We use QB for accounting and Rent Manager for PM (I often feel like it uses us - although there customer service reps are great).

As for his customer service I think there is room for improvement.  

Without an agreement: the Buyer is your customer and the seller becomes your client because they are the one paying the commission. 

I've looked into Guesty (which seems too expensive for what I hear to be awful customer service), Hostaway, Owner Rez, and Lodgify.

These are very personal decisions.I can't tell you how many times I had a seller pay me to go in and redo kitchens and baths, and then get called back by the new buyer to redo the brand new custom work....just because of color.I would just put the house on the market and price it a little high, maybe $20k...?

@Sarah Kensinger Good idea on narrowing down my ideal guest/customer like the book The Pumpkin Plan talks about.

Some people want cash-flow from day 1, some people want to invest long term, some medium term... all different strategies that would require a custom tailored approach.
