Selling websites on Flippa

Hello

I have previously run a local business in the pet grooming niche and I have decided to retire from this business.

I had ranked my business to number 1 on google for its target keywords (to do with pet grooming in my local city). My business website still ranks as number 1 and while I have tried to offer it to other local dog grooming businesses to buy so they can enjoy the ranking I have found that others in my niche are not familiar with websites, computers etc. and I haven't found anyone who is willing to take it on which is a shame.

I have 3 websites with good backlinks that I used to help rank my business website. They still have those backlinks in tact and I know people used to sell whole websites on Flippa.com

My question is.... is it worth trying to write a listing to sell the 3 websites in the pet niche that have good backlinks on Flippa?

Unlike other websites on Flippa my sites don't use Adsense and don't make any revenue.

However they do have good backlinks, original content with excellent English, are all setup on wordpress and if they were sold as a package of all 3 the new owner could simply adopt my GoDaddy account (as all 3 domains are there) and adopt the hosting (they are all hosted at 3 separate hosts paid into next year). So no risky domain pushing or transfer would be needed. And the new owner gets some hosting as well.

2 of the sites were PR3 and one was a PR5 when Google used to publish the PR.

Would this be of interest to anyone or do you think it wouldn't be worth my time and this particular niche probably wouldn't attract someone to buy them?

Thanks for the input
