are there any sites where I can directly search a list of qualified tenants?

I could pay a regular marketing firm to build a site, but since so many STR owners have this need, I have to imagine there's an off the shelf option rather than having a custom site built.

The online realtor sites give you dates but they are usually in the past and always have a disclaimer that " Auction time and dates can change".

But agree third party real estate web sites don't update status changes of a property based on my experience. 

You’re on-site for maintenance issues or tenant concerns, which cuts down on the hassle of traveling to a separate location.Loan Accessibility: Getting a mortgage for a duplex can be easier than financing other types of investment properties because you can use the potential rental income from the second unit to help qualify for the loan.Tax Benefits: Owning a rental property can open up opportunities for various deductions like mortgage interest, property taxes, operating expenses, and depreciation.Disadvantages of Investing in DuplexesPrivacy Issues: Living so close to your tenants means less privacy.

Scroll down the page and look for cities above the line for good performance.https://www.airdna.co/blog/best-places-to-buy-a-va...A word of warning - from someone who’s spent waaayyyy too long playing around on the AirDNA web site: they measure profit as revenue minus mortgage.In many cities, a large chunk of the high airbnb revenues come from very specific highly desirable properties in highly desirable areas (e.g., baller properties that are downtown or oceanfront or lakefront, etc).

Check out this on their site, if you think 50th percentile pricing is too high, you may want to try pricing at 25% and see how that looks.  

FYI: none of the sites listed above know the condition of the property.
