As an example, I was hired to be the project manager to handle computerized implementation of business units where their business model does not fit the normal.

Bathroom showers and tubs - tiled or fiberglass, etc.Flooring - Hardwood, engineered wood, laminate, vinylAppliances - MakeRoof - comp shingles, tile or ?

I will say this, I looked at shingle roofing last night quick as well.

(House was in Highland Park, Los Angeles)Purchase price: $600kRehab: $94k - Full rehab: new layer of shingles on roof, 13 new windows, all new doors, new laminate floors, new 3' front retaining wall, full gut kitchen (new cabinets, quartz countertops, tile backsplash), 2 full gut bathrooms (new tub, floor tiles, wall tiles, vanities, faucets, toilets, vanity lights), converted one closet into a washer/dryer closet, created a master ensuite with a hallway bath, opened up some walls, recessed lights throughout, scraped popcorn ceiling, installed new HVAC, interior paint, exterior paint, stucco repair, new landscaping front and rear of house, new wrap around deck, installed double french doors master bedroom and garage, to new tankless water heater, new exterior lights, updated light plumbing and electrical, new garage door with motor, and some other normal repairs like replacing drywall, floor boards, and replacing some wood trims like facia boards.    

I don't know the quality of the shingles she put on 8 years ago, but if they were cheaper 3 tabs, I would bet they have less than 50% life left.

Now that the shingles were on, I was going to have to live with the slight sag in the roof and we would have to address that on the price.

You might want shingles and they decided on tiles with a higher cost.

New shingles, several windows, re-level two second story apartments, new exterior entrances, three kitchens, three washrooms, flooring, drywall and paint, etc.We would consider two of the units habitable at the moment (even though three units are occupied), one is barely habitable, one apartment had a fire and requires refinishing and the commercial space is vacant and dated.Our goal would be to rehab the unit that was damaged by fire, then renovate one of the units currently tenanted and finally gut and divide the commercial space into two one bedroom units giving us a very nice six plex when completed.After plugging in income/ expenses and adding 8% for each vacancy, management and maintenance we end up with $100 cash flow as is and conservatively calculated $1600+ net cash flow once renos are completed if we do not refinance.At a 15% cap rate Value would be in the $135,000 to $150,000 value range.The  second property is actually kittycorner to this property via a back lane and is a completely finished fully rented fiveplex.  

The roof is ok for now, but is a re-roof job and the shingles are starting to "telegraph".

The property does need rehab work to the floors, kitchen and bathrooms, some window panes, some roof shingles need replacing, and entire inside paint job.I just met the contractor this Monday July18th, and am awaiting his estimate.
