If you are looking to be a full time agent, your first year is typically slow, but then grows exponentially from there as you build your network and get your systems going.  

Remember this is your property not the governments.In your example if you believe the older individual is a better choice based on their personality and how that may impact your property you are in fact not selecting them based on age at all.

Just remember a team they better be feeding you business as you will likely have a cut with the brokerage you hang your license with AND have a cut taken out as a percentage with the team.

The time came (growing family) and we just closed on a new personal residence and paid for it using 80% LTV. 

And remember, your "all in" price will ultimately be higher than 120k depending on how much work is needed.I would recommend talking to one or more mortgage brokers, or loan officers at banks you already have relationships with, as you may not have to do a 20% down conventional mortgage but may be able to do FHA or Conventional 97.

Judging by my best case scenario I will have around 29 units about 6% to my goal, but the knowledge and connections will hopefully help this grow exponentially to help me reach this goal by age 35. 

I've been an investor in the Lyncbhurg, Virginia area for more than a decade and I can't remember the last time I bought a house without first finding it on Zillow.

Best option:  (I know it’s not single family, but it’s a super fast way to grow your equity AND passive income) buy a multi family (2,3, or 4 plex) as an owner occupant, live in it for the obligatory year, then buy another, until you just have to have your own house.  

Thank you @Chaz Mathias  I appreciate it, but as you know there is always more room to grow. 

But in a fast growing market like Orlando Florida or Dallas Texas it may be desirable to be close to new development, that is what is referred to as the "path of progress."
