Point being that property you acquire 1-2 years ago is likely to be subject to deferred maintenance and capex, so their "long term" performance in rankings 1), 3) might skew poorly in year 1-2 but may pickup  after you've found and fixed all the hidden issues.I know if i did this exercise across my portfolio, the recently acquired ones wouldn't be fairly "stacked" because of all the year 1-2 cost build up from what the seller deferred, but have good chances at being future performers in years 3-5.Maybe that's why you have 2) and 5) but curious your general thoughts here are for evaluating this. 

Finding the right realtor/wholesaler can be a huge advantage, especially someone who knows the local market trends and can spot areas with hidden potential.

I recall reading something along these lines in The Economist, pointing out how hidden fees can vary widely depending on local ordinances.

For example, if you’re holding a triplex in Irvine, the strategies are going to differ greatly from someone managing high-end rentals in Newport Beach.Costs and Terms: Watch out for hidden fees.

I Came across a video from the bigger Pockets team, this video gave a ton of gems.

This was my first property, and while it's been a great learning experience, I made several mistakes along the way—ranging from choosing a realtor who was more focused on closing the deal than finding the right house, to having a poor inspection and overlooking issues hidden beneath the surface (literally).

It might be a hidden leak or even a running toilet causing the spike.

Now this can be done in Urban areas as well.. those in the Know can find these hidden lots and there is some big money to be made at this.

The numbers you see in pro formas or calculators often don't account for hidden costs like:-Major repairs and capital expenditures (roofs, HVAC, plumbing, etc.)

I can fix any issues we can see and know about right away, it’s the hidden ones that older homes just tend to appear.
