You have no way to prevent this.If you say the structures are not less desirable than the surrounding area structures then supply/demand will quickly drive prices way up.

The rest of the market has higher demand than product supply currently.

If the current trend continues supply of housing will outstrip demand resulting in lower prices and lower rents.

The duplex with the equity was purchased the old fashioned way in 2016, 25% down.

A lot of supply places offers designer discounts . 

In fact my wife reminded me yesterday that one of our 'investors' has never had his work/tools/supply van broken into because he has a 100 lb python in it.

If you are part of a team, and the team can supply the local knowledge and logistics, fine.

You can get local metrics on occupancy rates from Airdna.co and good old fashion due diligence on VRBO/Airbnb/Homeaway but your ADR and Occupancy is really going to be determined by the experience, value and eventually reviews you are able to garner from your guests. 

Persons per unit: This is a basic measure of supply and demand.
