I don't think the intentions of the buyer should concern you.
It's a simple reverse-auction strategy of initially setting a high price and lowering it until a buyer bites. This is how you get the highest price. The realtor suggesting you start at the low-end price might deserve to be fired. They are out for a quick buck.
That said, you have to manage the costs of the building while you're waiting for someone to buy it, so don't hang out at the high end for too long. I suggest initial pricing at $185, and in two months lower to $175, and if that doesn't work lower it to $165 two months later. If you end up taking $155 after all that, then at least you know that was exactly what the market will bear.
How To Raise The Price You Get
Rehabbers need to reduce their uncertainty about a property like this. Specifically, they are unable to see all the damage, like melted wires or pipes inside of walls, or how much of the roof or wall lumber must be replaced.
You can reduce their uncertainty by (1) removing all personal items, furniture, and garbage from the building, and (2) starting demolition by ripping out sheetrock, ceilings, carpet/flooring, cabinets, insulation, doors, etc. The emptied-out or stripped-out house will be much easier to estimate, causing the rehabbers to lower their contingency budgets and offer more for the house. Additionally, whatever labor you perform is labor they don't have to perform. Order a dumpster, wear gloves, and an N95 mask.
Of course, this effort is wasted if the buyer wants to demolish the house, or if a buyer appears at your high price range. So you only do this if it's been on the market 3-4 months. And, frankly, this kind of work is not for everyone. It's dirty, dangerous, labor-intensive, and smelly.
Finally, take lots of pictures for the listing. You need 20+ pictures showing both the damaged and undamaged areas in great detail. This screens out the unserious people while also giving the serious people some information to work with.
