Get your dryer's exaust cleaned before you open up the unit for rent and periodically therafter.

Then go price your labor plumbing electric, roof, finish outs, and landscaping.     

We also had some exposed wires under the house that required some minor electric upgrades to bring to code.

Still you’ll need to fix any plumbing, electrical, door etc type issues which likely are in bad shape.

It’s currently a mess but the f/c will clean it up. 

@Derrek J HooymanI'd personally wait til after the tenant moves out again so that you have a clean slate to work from.I feel like value add recommendations have to come from you or your realtor...aka someone who has seen the property and ran the numbers. 

Add charges for rent for the remaining months, estimated utilities, estimated cleaning and repairs and cost to re-rent (in our case: cost to PM is 1/2 a month's rent).

I purchased rentals that are all clean BRRRRs and meet the 1% rule then grew my portfolio to over seven figures.

Junked it out, cleaned up landscaping, drywall repair, texture, paint, new interior doors and trim, new waterheater, new floors in kitchen. some new floors, countertops, new roof, painting cabinets.

It sounds like you might already be aware of this, but the only time you can put a rental property on a Schedule C is if you provide those "hotel-like hospitality services" that you mentioned, which means things like not just cleaning between guests, but daily cleanings during guest stays, and/or providing them with things like meals or entertainment during their stay.
