I have a 2bd 2 ba vacation rental worth of furniture supplies, living room, kitchen, laundry room everything you would need turn key for a airbnb or VRBO where is a good site to sell it all in one and not dirt cheap? 

I am a first time real estate investor looking the following property : https://www.redfin.com/OR/Forest-Grove/2418-Cedar-Cir-97116/...its a pretty large duplex in Forest Grove OR,  the trick is though, its on a lot zoned for a 4 plex so I am lookinginto house hacking, converting into a triplex, then living in one unit while renting out the remaining two unitsThe left garage has been converted to living space, with a living room, half bath, a laundry room with a sink and some counters/cupboards and a bedroom, it is a part of what was an existing 3bd unitIf I were to acquire the asset, I would first attempt to convert that space into its own unit The line items as I see (be in mind, I am totally new to this) would be to >put up dry wall where the door to the rest of the house is,>add a shower to the half bathroom >install a water heater in the adjacent 3bd unit> install a kitchen in the laundry room, (stove , oven , sink, counter space)>add a shower to the half bath Assuming I can convert it to a 3plex, I could at-least cash flow on my investment after I leave My plan would be to put minimum down payment of 3.5% (FHA loan) that way I can have a decent amount of capital free to do the renovationsThe only concern is when I crunch the numbers to get my ROI, I have no idea how much its going to cost to convert the additional living space to a third unitAny experienced investors here know how I can estimate this before I try to make an offer?

The kitchen was taken down in the unit.

It was already perfectly set up for it with almost all water hook-ups in place already (wet bars, previous basement kitchens, etc.) and I mainly just had to remodel and put a few exterior doors in place to separate areas.

no walls were torn down, no new kitchens or baths installed, 2 had no new floor coverings installed all 3 had recent new electrical service. 

It's a B- class neighborhood.Apparently there is some dog pee odor and some bad scratches in 2 of the 3 bedrooms and water damaged next to the kitchen (which is tile).The bamboo flooring flows through all the rest of the house except the bathrooms and kitchens.Would would you suggest?

They are allowed to not include 'complete' bathrooms or kitchens, instead sharing those with the main house.

Compare: how nice the kitchens & bathrooms are.

We mainly work on bathrooms and kitchens and restore what the restoration companies tear up when they mitigate water damage.
