There is no given answer here, because the whole property needs to be relatively consistent.Kitchens and baths are the common answer, but if they are passable and you choose to invest in them anyways at the expense of peeling paint (or off putting exterior color) and overgrown landscaping, the appraiser and tenant will be walking up with a bad taste in their mouth, thereby not valuing the interior work you have done.But think about the general flow of someone looking to rent: more bedrooms will typically dictate more rent.  

If you finish the basement with a kitchen you could have a mother in law with a walk out and a garage downstairs.

An inspection contingency allows you to walk away with escrow but not recoup expenses.Best...

With my condo, I believe because they can walk right out of the building to the slope, in many eyes it would out rank a home where you can't do that.

It also has a nice loft with ceiling that's high enough that you don't have to hunch over to walk around.

Pay a contractor to walk the property or multiple to get a idea.

.: I'm curious how CA agents can make a living with laws like AB2992 that state:"If the out-of-pocket costs to pay their agent remain too great and the seller and buyer have not yet reached an agreement on the sales price and/or terms, the buyer may walk away from the subject property provided there is an exit clause, proceed without representation, or approach the seller's agent about possible dual agency representation." 

Happy to look at properties or do video walk throughs.

I later flew out there and walked the properties -the properties and neighborhoods look much different in person than on video. 

First, the tenants signed a legally binding contract and do not just get to walk away on a whim.
