Once you have this 'firmed up' go out and build yor team - contractors, title agents, attorney, banks (financing options), appraisers and of course a good qualified Realtor...Hope this helps...
Spend your money on the kitchen, and in the bathrooms don't skimp on the toilets. Also, with central air, put a 1" condensate line instead of the usual 1/2".
On a complete remodel, your biggest $ are in electrical and mechanical. Adding additional closet space is but a few 2 x 4's, but adds great value to a lady renting a place, for clothes, and for a guy it may be for sports stuff, and kids additional place for toys. This means way more than fancy molding, etc.
So maximise the functional, keep your interior buildout remodel total cost to $80 per sf or less.
