Due to my age, I need to liquidate some of my assets.

Even though you have a family and that's a huge responsibility, you can take some lumps in the beginning (at your age especially) & still be okay down the road.

Is the aging systems or differed maintenance?

Your average age of accounts is a pretty significant % of your credit score (which means if you had two credit cards and your average age of accounts was 8 years, but then you apply for 4 new credit cards today, your average age of accounts will take a hit thus causing a drop in your credit score too). 

I typed in "do I want to get into real estate" into google and came across this website along with Brandon Turners article, "How to Start Investing at a Young Age", which got me motivated to start learning now rather than waiting until I am older. 

The puppy will have destroyed your carpet by then through lack of house training at that age.

I am about to turn 34 and I feel like I am already late to the game if I want to really build wealth and retire from the corporate world at a decent age. 

When they interviewed Mike Flowers from Florida I loved the confidence he spoke with about how much he loves doing what he does and the fact that we were about the same age made me realize that I can do it too.

I could be off base but that's my take on it.1,500 is not a lot for someone who could actually teach you the business.. but you may want to talk with some local folks and offer to work for free in exhage for some education you may have some takers on that.But at your age I personally would spend the money getting a RE license and go to work for a top producing broker on a team and REALLY learn the industy.. wholesaling is not a life long pursuit with most folks...

That is very good.Repairs will depend on the tenants and on the effective age of the building.
