I'm looking for feedback on what distinctions need to be in a lease like this.

The age of the home and its two decade vacancy has led to more damage to the structure than we originally thought.

This can tell me a lot about the age of the plumbing, roof, HVAC, etc before actually walking it.

Depending on your age, that may be a small amount at the beginning, but it gets to be a bigger percentage of each account as you get older and your life expectancy gets shorter (according to the IRS table). 

Instead, just last year, at the age of 38 and with a wife and kid, I househacked a duplex in Hancock Park.

We, as a Roofing Co, talk and deal with MANY clients that have aging roofs, and yes are fine, but the ins co is either wanting them to: replace the roof; pay a higher delectable; not have coverage for the roof; or drop them!

Little things can make a big difference as far has how long a house stays on market: school district, lot size, age of the home, flood zones (avoid) etc. 4.

@Natalie Vane I admire your enthusiasm, and envy your forward thinking at a young age.  

Properties in this location may vary in age and upkeep, impacting maintenance costs and potential rental income.

I am able to do a CMA (Comparative Market Analysis) for you with specifics based on what you are looking for, however- I just need square footage, zip code, number of bedrooms and bathrooms, neighborhood, year built and age of home/upgrades and improvements to compare.
