I've done Crypto, stocks, businesses, ecommerce, trading bots, ponzi schemes etc. 

Here in Portland, there are a couple of different landlord groups/companies that offer pre-made forms.

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

Two days later our offer to purchase the property + adjacent empty lot was accepted.

Many companies offer 300K max and above that they'd need an umbrella. 

Hi michaelI've been using orign8 at $250/month and they have a lot more to offer like lead gen, automation, missed call text back, basically an all-in-one inside sales marketer. but I don't know if it's available in your area. 

In searching for a new solution, I came across baselane.com and it seems to solve for most of the functionalities offered by Stessa+Avail.co.

They also offer courses and webinars.

If you for sure want to sell it, there's not much to do, the best offers you are getting are what it's probably worth. 

Your niche depends on location and amenities you offer.
