I have a very detailed log book that lists all of the items mentioned that i've kept since the beginning of my project.

You will not always be able to request assistance on BP as some items need to be dealt with immediately. 

Quote from @Brendan Jones: For the homes, and or properties that you will use as a primary or a rental property one big thing I look for is infrastructure in the area, extrinsic value (I.e. hospitals in the area, schools, and job market), and the last thing is creature comforts for people (I.e. is a store to get groceries 1 hour away or 2 minutes away).

Clearly in general the class D will have the higher maintenance/cap ex.What I recommend is every RE investor populate a spreadsheet with current replacement costs and expected average life span in months for every item on the property to determine the expected monthly maintenance/cap ex. 

Sea and mountain views, nearby public transport, the hospital, restaurants, cafes, grocery stores, 5 min walk to the beach and 20 min walk to old town.

Unless you can knock all of those items out in the next week, price competitively in the market and are in a hot area. 

.- Cost segregation has limited benefits: While cost segregation can still be used to separate personal property items like furniture and fixtures, ADS rules apply.

Raising rents on existing tenants while maintaining good relationships with them and fixing deferred maintenance items.

There are a few more “big ticket” items that need to be considered (Minisplits & landscaping) but most of the major costs have already been accounted for on this property.We currently have a 30 year conventional mortgage with a 7.125% rate on a purchase price of $750k. 

So for me if I'm budgeting $250,000 on a remodel (with a very detailed line item budget) then I'll add another $50,000 contingency to cover the unknowns.
