I was a banker for 25 years and my wife's degree is in Interior Design.

Saves you from having to either paint or wrap large portions of the exterior.3) Varnished trim on the interior. 

So this is a investment/ flip I am very serious considering doing (already started escrow). the mls is 190048729 https://www.redfin.com/CA/San-Diego/6805-Fisk-Ave-92122/home/4895069With a purchase price of 845k with 3500 closing costs total remodel (done well) 96k20k kitchen15k (2) bath10k flooring12.5k paint/baseboard7500 on windows and door (inc. pre hung interior)13k roof15k plumbing (needs epoxy reling to the main)3k landscapetotalling 950k ish total cash outlayanticipated sale is 1.1 milgross 150k-minus seller fees 55kand contingency 5k making nice profit range 90k with a worst case sale price of 1,050,000 still in 40k ish I guess my issue is being the 3rd deal I am on so far (usually the 500k range) the larger # make me post up for another viewpoint for my SD real estate pros to say this good or not. would love to hear from 2nd opinion look before we close.

Study interior photos if you can find them, that is the most valuable data out there.

:)I second @Javier Rosales' post - Very shortly I plan to add an interior, non-load bearing (hopefully with some soundproofing?) 

The interior has new carpet and paint.The exterior has stucco and dual pane windows.

Will need sheet rock, trims, flooring, cabinets, toilets, fixtures, interior doors, appliances.

This leads me to believe that if and when she moves out, I will have to replace the carpet completely and also repaint the interior walls.

NNN expenses for a tenant would include essentially everything on the interior of their space... lightbulbs, janitorial, HVAC contract, plumbing, etc.Feel free to reach out directly if you have any other questions.

That being said, I know of plenty 4-unit properties for sale in that same price range that are in C-D areas so $1.1M in an A area sounds like a slam dunk but I'm sure its been on the market this long for a reason - i.e. poor interior condition, non-cooperative tenants, title issues, etc.I'd be happy to help you look into this deal a little further.
