Although I believe you’d need to keep an interior door access to the upstairs as the house is zoned single family.  

Most of my projects are just opening, adding or rearranging a couple interior walls, and if we're not doing anything structural I shy away from permitting altogether.

Part of the cost of doing business.Now if your city's ordinances require rentals to have gold-plated toilets, motion-activated interior lighting, and new interior paint every 2 years, then yeah, I could see how that's unreasonable.

This is super important long-term to maintain the integrity of the interior.

I plan drive by and see the outside but I may need to run my numbers best I can with out seeing the interior and make an offer to get under contract and than make any adjustments during the inspection process.

Expect a full interior repaint every 3-7 years, depending.I would recommend you ask your PM to itemize the work, and see if it sounds right to you and other landlords in your area.Regardless, you should always understand your PM's financial incentives.

We did a full kitchen, 3 bathrooms and repainted the entire interior and exterior.

Assuming these quotes are on-par with the market, that leaves me 29K for electric, plumbing, windows (maybe), and interior. 

Had a leak, for instance, that sogged out an interior ceiling.

I'm itemizing every single thing I can think of e.g. water heater, lights, faucets, counter tops, permits, surveying, plumbing, electrical, septic, lights, inspections, gutters, dump fee, insulation, framing, exteriror finish, interior finish, networking, solar (although it isn't really cost effective, I really really want a tesla roof), chimney, heat pump, windows, interior doors, exterior doors, garage doors, locks, sinks, showers, etc. with exact models and prices to help me get in the ballpark.
