I've purchased this property and after a too-long escrow period, the property which is the subject of this thread is now mine.I've started the rehab, hiring an architect whose services I used during the due diligence period.My question to the Bigger Pockets community is this:    The roof has had holes and water from rain has come through for several years as the previous owner abandoned the property.   

Basically everything is new; roof, siding, windows, electric, plumbing, HVAC, kitchens, bath, flooring etc.

T&G Roofing did my parents house a few years ago.

It might help to think of a few different categories:legal/land: encroachments, zoning issues, codes, neighborhoodphysical plant: wiring, roofs, HVAC systems, septic, gutters, deferred maintenance, lead, foundationsfinancials: tax changes, assessments, insurabilitytenants: arrears, deposits, ongoing disputesMy votes for most overlooked?

With the money we had left we also secured and purchased another duplex that was an reo foreclosure. 3 closings all done in the height of the Covid pandemic, it was very nerve racking, but we are very happy with the acquisitions.

20 x 20 would be 400 .Sometimes carports don't have the best roofs,  They need to be beefed up with extra supportto take on the extra weight of the conversion. 

It's (2) 3-unit buildings and (1) 4-unit buildings with metal roofs and slab foundations.   

If the property has newer appliances, HVAC, roof, siding, driveway, etc, I will account less for CAPEX - maybe around 5% and if they are old I would account for 10-15%.

I received a couple of different quotes and went with Josh Chapman as his quote was $1675 for an older duplex with a newer roof.

This can be risky but if it's a newer home or one that's obviously been well maintained and you've checked the permits to determine the age of the larger components (roof, plumbing, etc.) it might be worth the risk to get in the game.
