The supply of rentals would be impacted, but the final impact will depend on the local market.

I don't know if that is included in the total rent numbers the owner supplied. 

.-- The influx of STR supply has certainly brought down Airbnb revenues the last few years for everyone.

Additionally, the supply of homes for sale is constrained because of this and will be for some time putting upward pressure on prices in most markets.Thinking about renting your house in Seattle would be wise as someone else will pay the mortgage down, and rents and the value of the property will go up over time.

@Shayan Sameer,The really brief answer is that most of TN is pretty affordable apart from Nashville, which is an expensive, supply-constrained metro.The median home price in Chattanooga, for example, is about $300,000, which is a little above your $200,000 budget.

If you supply the machines, I recommend increasing rent $100 or so to compensate for the purchase and maintenance. 

There is a $200 cancellation fee to cover the extensive materials and supplies we give you when you join. 

We know supply is a big issue with low inventory across the whole country.

If there is more demand than supply, this will be the outcome in desirable areas. 

I will be living in the guest house, while renting out the main.Both units are without washer and dryer units, my question is, do I supply them in the main house; or let potential tenants figure that one out?
