The only marinas out there that will be for sale are either way overpriced due to massaging of the paperwork or or in some type of an environmental let's call it " mix up".  

I prefer to ask my local lawyer who specializes in landlord/tenant law and has leases that they used for decades on thousands of cases and they have been changed and massaged for local rules.

Too often newbies want a deal so badly, they massage the number to make the deal work.

Contact him and give in 72 hours to return them and tell him if they are not returned, you will contact the police and take him to court.Then start looking for gently used appliances for sale.

I offered him $540,000 and I gently asked him if he would finance the 20% down, then I would pay him 8% interest for 1 or 2 years.  

Tenant moves the boxes into another room.Have your workers gently move the furniture and cover with blankets.I don't know how messy the window/door guys are but maybe they have to jigsaw out the old windows, plane the doors and create dust...

This would be more soft sell - gently mentioning you are investing in apartments - just plant the seed in an off hand way - no sale script no close - just light conversation over a beer or coffee or at lunch.

@Brandon ReedPre-purchase: Not running their numbers correctly, or "massaging" the numbers to make the deal look good.

No, you don't need a 72" curved TV that massages your retinas or the new iPhone 7 which is slightly water resistant.I'd rather take my 15% cash on cash plus gains on equity and appreciation over worse returns in other asset classes (public and private equity, bonds, etc.).

Got all kinds of gadgets, radio, CD player, foot massage, body jets, rain showers, ozone sterilization, steam, exhaust fan, telephone etc...a new one sells for $3000.
