AirBNB and Furnished Finder are two resources to see how many MTRs there are in your area and how much they charge. 

Make sure to check all the available resources here and feel free to jump into the discussions.

I have looked at sites like Realtor.com, Redfin, and Zillow but it doesn't provide OR doesn't give a pinpoint sale price on properties.

These sites are a complete waste of time and money.

However, this must be paired with a dedicated and robust negative keyword strategy to prevent your ads from appearing for keywords that ARE NOT RELEVANT to your investing business.For the sake of this example have a look at this attached picture below:In this picture you can see that this ad shows up on the keyword “House for sale near me…” which is not something a seller would search for (not to mention a distressed seller).

@Michael Koski BP has a link for finding someone for those "long walks on the beach", https://www.biggerpockets.com/blog/2015-04-01-biggerpockets-love-dating-site-real-estate-entrepreneursIf you'd like to chat about Detroit, DM us:)

There are seven tests, however the most relevant tests for STR investors include:Perform substantially all the work related to the activity.Participate over 500 hours during the tax year.Participate over 100 hours during the tax year and no one else participated more.If your property meets one of the exceptions above AND you meet one of the above tests, you can qualify to treat your rental activity as non-passive.

You could network through sites like bigger pockets or go to local real estate investor group meetings to make connections with people who could potentially be viable partners.  

You can also search the county auditor and treasurer's site to see if the taxes are being paid or if they are delinquent.

I can't even remember when I was on that site.
