I'll do a better job of watching self promotion in the forum, you are correct.   

I suggest they pass out flyers promoting their services.I had a tenant that was able to fix broken windows, I helped him with a flyer, told him to get a nice workmanlike uniform to look professional.

That's why I always follow up with DRIVE when we promote/share this strategy :-) Even Sharad invests 45 minutes outside of his zone.

Airbnb is trying to promote longer stays so if you don't have longer stays targeted on your calendar, you'll want to do that - you'll probably even get a boost in their search rankings for your area.

Just want to know if I need to find a realtor to promote my house for renting out, if I am a beginner. 

If the speaker shows you palm trees, blue water (swimming pools or beaches) and expensive cars and promises you never ending sources of secret deals and niche investment opportunities, you probably have just discovered the promoters of the gurus of real estate.Before you pay the full annual fee, show up and check it out for one night.

I"m still considering purchasing through Homeserve as well since cost is so low and no deductible, and covers water line and sewer......https://www.baltimorebrew.com/2014/09/17/concern-and-confusion-as-city-promotes-water-pipe-warranties-from-one-company/

A reputable contractor who wants repeat business will absorb those costs to promote goodwill with his customer and will make up the loss on future projects.

Attend industry events, network with other professionals, and promote your business online.

I personally steer clear of Angie's List, Yelp, BP Vendor, Dave Ramsey Select Vendors, or any other service that charges the vendor for membership and then promotes the list to the public as if trust, excellence, and performance have ANYTHING to do with the list selection.
