I don't have an answer but I want to applaud you starting at an early age!

The other thing is our health gets worse as we age, people get sick.

Kevin,That will depend on the age and price of the home and the amount of deductible.  

Depending on the type of loan (conventional versus FHA), they have very specific requirements for the condition of the property - from the age of the roof to the condition of the paint. 

You will be sacrificing getting on with your real estate experience and holdings, but would be doing a good thing for aging parents and will have a good asset paid down and ready when you are both ready for other living arrangements.  

I wish I had your drive at that age.

Age is usually not much of a factor and units built within a few years of each other won't have an adjustment for age.

Yes, I started working at a young age.

You are starting this at a good age to live out your dreams.I am 60 years old and I live in Dallas County Texas and I have not traveled much out of this state.  

Just give them the details of the property, beds, bath, garage, exterior, age of roof, as much as you can, your asking price, whether seller or buyer pays closing, and the rest is on their end.
