Download your landlord tenant laws for your state..Each person that's over age of 18 is listed on lease as tenant.. all equally responsible for rent.

For example I would want to know more about the building itself such as clear height, construction type, age of construction, is it sprinkled, how much office space?

Depending on the age of the house etc these numbers usually work for me In my area.

They're the ones that convince the landlord to sell their rental property to someone else, because the idea of cleaning up after their mess is just too much to bear for an absentee/ageing/uninterested landlord.

I want to know if by starting and using an LLC or Corp would I be able to bypass my age troubles.

For tech illiterates in this day and age, I think a check/money order in the mail is about as advanced as you can safely get.

I know it would be terrible when it comes to selling, however whilst renting it, it would be fantastic.

Most homes in an area are consistent with age, design, quality.

I m also around the same age group as you are.

However, the information may or may not be important.Everything else is just publicly available data anyone has access to.Comparables are just recently sold homes (similar in size, style, age, etc., sold within the past 3-6 months).
