I would guess that low-end segment in your market is probably dominated by owner-occupant non-investors.Consider that brick wall a friend, because many people walk around it and end up losing money.

Find a realtor who works in the investor segment and has a track record in your market. 

I turn down 3 deals a week for people wanting to sell us their mobile homes, and I do not like passing up opportunities but have not found how to move this particular segment . 

Small cities are too dependent on narrow market segments and single employers.

Kansas City is a relatively large market, and property management services can be relatively segmented as well. 

Nobody in our C/D market segment here in the 'Burgh except perhaps organized crime. 

Basically, you need to switch over to an entirely different segment of the lending industry.

Perhaps a large segment of people propping up the Boise market have moved there in the last two years from California, Washington, New York, Maryland, etc.

I guess this is what keeps agents in business and computers from running everything. one thing you could differentiate is to divide the segment into home price 3/1 and above or below ; and/or with price above median and below median (using  zillow as comp) then you would see different picture altogether.This is why I dont buy narrative from news reporting anymore as they're very inaccurate.

However, I can imagine that some types of STR may be targeted toward a high income segment of the population.
