It was built in 1973, is in fantastic shape but dated, has a 4 year old roof, is in a good part of town, 1,100 square feet upstairs as well as down and both apartments are 2 bed 1 bath.  

Ensure the plumbing and electrical connections are regularly checked for any leaks or faults.Lighting and Fixtures: Modern light fixtures and ceiling fans add aesthetic value and comfort.

It's a duplex, one side he is setting up for STR and duplex needed work, such as new roof, siding, etc.  

But at the same time, if he is still  getting more money from unexpected investors who will likely lose money as well, then I think it is great for Ryan to shout from the roof tops a voice of warning to others to beware of Scott Carson by sharing his personal story.  

The pros is it's got a great exterior with steel siding and a new roof. also has a 1200 sqft shop that is insulated.

Unless you do upgrades to depreciate, like another roof, large appliances, AC unit etc.

Age of roof, electrical, heating & plumbing systems?

The HOA funds are limited and if something happens, there will likely be a special assessment; roof and/or exterior paint are the big ticket items that are near end of life according to building assessment.

Per home it goes away with one ac unit, or new roof, or a month of vacancy at each property, especially with unit turns.
