I have a property in Missouri (it's on the marketplace if you're interested!)

Should Tenant neglect or fail to perform and observe any of the terms of this Lease, Owner/Owner’s Broker shall give Tenant written notice of the breach, delivered to Tenant personally or mailed by certified mail, requiring the Tenant to immediately remedy the breach or vacate the Premises on or before a date at least fifteen (15) days after date of the notice (except in the event the breach is for failure to pay rent in which case the five (5) day statutory notice shall apply).

As a former brewery operating from 1883 to 2001, Pearl reflects a vivid past while embracing the future with LEED-certified complexes mixed with historic architecture. 

You might want to do a certified letter via post office wherein they have to sign for it, or hand deliver a letter wherein they sign a copy that you keep. 

first you have to find ones that will work with foreigners.Peak in KC will I believe Lima ONe willalthough keep in mind real estate lending has been in fested with FAKE lenders and scammers.here are the red flags:1. interest rates far lower than market like 4 to 5%  this simply does not exist in the market place they just are sucking you in thinking you found this unicorn lender.2. reason they can lend that low is you buy insurance to guarantee payments.. this also does not exist its a fraud.. there is no such product.. 3. offer to show a picture of the person your talking to holding their ID.. again just smoke and mirrors.4. tell you what you want to hear but need 500.00 to 800.00 deposit to go further.. you send that you lost it.5. bad webstie or no website.. poor English etc.

The only additional site I post listings on is FB Marketplace. 

You should also send a certified letter to the vacating tenant stating the rent has been retained for the missing rent. if you don't have his new address, send it to the house so you have proof you sent it. keep the receipt.

I always felt like if you made the upfront investment, especially with craigslist and Facebook marketplace having such cheap furniture, that students may pay a premium for off campus housing that doesn’t require them to buy furniture but don’t know if you think it’d be more trouble than it’s worth.

I would use Facebook marketplace and Craigslist to find new tenants.

I just listed the 9 houses in the B- neighborhood in BiggerPockets Marketplace.
