You already have a huge leg up on the rest of the world (determination to make it in real estate at such a young age)- just don't give up!  

The age of the house is important, because even if its a well-maintained house, its going to have an older style floorplan.  

One of the main reasons i'm looking to get into real estate investing is because you are providing your community with distressing properties and adding new occupants and continue raising value of properties in the area.One situation that really caught my attention was a investment property that happened right across the street from my home.an investor or someone bought the property for like 140k and just resold in less than year for 450k.it needed some work but nothing out of this world.roof,kitchen,flooring,A/C,paint,clean up pool.How can an individual at the age of 24 get started with no credit or money down?

Im sort of new to this myself and I'm about the same age...

In case of residential real estate, it is 27.5 years.While this is not intuitive, the 27.5 years starts at your purchase - has nothing to do with the age of the property, and is based on the depreciating portion of the purchase price, which excludes the land.

Banks don't treat them so well as they start to age. 

The exact same people who say new-age politically loaded  terms like "predatory lending" are the exact same people advocating the federal backstopping of  loans to everyone regardless of academic qualification,  or the desired course of study.  

Plus you are going to need to look at the age of the roof, age of the water heaters and age of the boilers.  

The best option is always to talk to other investors in your area, with similar deals (age, units, condition) and get real numbers, or to review the financials from the owner, if they have any.

The application asked for my age.....TWICE3.
