I am planning to sell my primary residence I purchased on December 2020.

So, whether you're buying, selling, or simply dreaming, take that leap of faith.

I would not remove the bridge as it is steel and I plan on selling the house in 3 years to avoid capital gains, and the bridge is required to access the entire yard.

When offering a seller options you are selling speed vs convenience, do they want to move on fast?

This approach aids in easier property management and selling, but increases administrative costs and tax complexity.

A good deal will sell itself, post on your local Facebook investor page and call up 10 realtors who have clients looking in that area. 

I am having hard time trusting the business that are already on the market for sell.

Its really no different than if you did it on your own home, then needed to move so you sell it. 

I would not want to buy something that was illegal or have a agent sell me something when they knowingly know that I am not going to be able to STR it. 

It is partly your job to "sell" him on it, and partly an education and relationship-building game from your end.Also, take a look at the buildings history, when it has last sold for, if it has bounced around on the market or not etc.
