Visualization of all attic and crawl spaces is coming down the pipe.If you re-analyze the value using more recent comps, what value do you get?

Now I do a recorded webinar, so it's similar to the conference call concept but with a visual component so I can share photos of the project, charts, and data during the discussion so that viewers don't have to flip through printed material to keep up with the conversation.

. (~4-6 bedrooms here).B-level: Similar criteria to A-level but without the custom built homes, 2-income families can afford to live here and raise a family, backyards for the kids, 1500-2000 sq ft houses (~3 bed/2-bath homes).C-level: Majority of houses under 100K, visual repairs needed in this neighborhood, 1200 sq ft average, houses close together, some properties worn down, grass not cut, porch awnings sagging, concrete stairs crumbling a bit.D-level: Struggling neighborhoods, garbage on the streets, bars on the windows, higher crime, crowded areas, downtown city area, wouldn't want to walk around here at night.F-level: War-zone, "get me outta here" property, makes you nervous to enter the neighborhood even in daylight.That's my basic approach when I think about properties and what areas make the most sense to invest in.

Don't worry about "tenant insistence" as you have visual and written proof to the contrary. 

Need advice on what types of metrics to show on this data visualization that I'm creating to help find good areas to invest in.

My name is Chris, I'm currently a 23-year-old college student in Los Angeles, California, studying Visual Effects for the entertainment industry (i.e., special effects for movies -- y'know, blowing stuff up).

I must say I'm located in Miami but I'm willing to travel if I need to for a visual inspection after getting an offer accepted, if I get to present it.Thank you for your help in advance!

I follow the six principles outlined in 'The Miracle Morning' (Silence, Affirmations, Visualization, Exercise, Reading and Writing).  

I believe it is not less than 30 based on visual memory.  

-Sidewalk visual inspection - No apparent major issues/looks well kept-No rent controlBesides inspection/title search and other basics, are there any other formulas, things you like to ask for, things you've learned from mistakes with multi-units, etc?
