I understand your comment about the length of time versus visuals of the work completed.

-calculate ARV’s - Future rental amounts based on visualizing the finished product - estimating a complex rehab- managing a complex rehab or managing a contractor When you don’t know what you don’t know the BRRRR is a great way to lose money quickly.

He said he uses candles daily and happened to be on during the walk…I question it but house didn’t reek and there was no visual damage to walls or paint.

Now, these things get a visual inspection from the appraiser.  

Above ground pools aren't as enjoyable or as attractive to prospective tenants (both visually and usage wise).I would vote to dismantle it and sell it for whatever you can get.

@Alonso Figueroa it can be helpful to check with the County recorder to check chain of title and ownership and the County assessor to check property taxes (itemized breakdown, assessed value etc). https://communitycrimemap.com/to check crime visually. 

My background is finance, marketing, and visual storytelling.

Imo, beach/sands/rock/ocean are more visual and stick more than just 'shore'. 

To answer your question directly, my top skills are project management and risk analysis, process improvement, and data analysis/visualization of marketing and business efforts. 

Focus more on what provides the best return on investment during a rehab.Having the essential systems (Foundation, Roof, HVAC...) maintained and in great conditions is more important than the visual appeal of the property.
