All modern furnaces have more repairs because of the complexity involved in safety and efficiency.I have proactively replaced 40 year old HVAC systems, because it always seems they go out in the cold of winter or heat of summer - at the worst time! 

Although I am still in my 20's myself, if I were to think back to when I was in college, I would probably prefer to be involved in real estate but not FULL IN.

Now, I know that I am unique and I enjoy managing my apartments and not everyone can do that,  or wants to do that,  and maybe some folks dont have the cash involved like I do.... 

But if you intend to get involved with Commercial properties, 5+ unit rentals, fix & flips, or new construction you should consider agents that will be able to help with those areas as well.  

I'm looking to network and build some beneficial relationships for everyone involved.

(looks like yours will)- Since it will involve my time to some degree, what approximate &/hr do I expect to receive for my time?

But I must commend you, you did handle it the correct way getting a professional involved. 

As for the tax side of the question, your CPA can guide you on the tax benefits and risks before you start the Series LLC, but they should be very involved in your record keeping during the year to make sure you maintain separate records of the Series LLC while they are in operation (read the Texas Series LLC statute regarding record keeping required to maintain separate Series status).

I guess you could contract around that, agree to refund money if previous owner redeems, but still painful for all involved if it happens. 

My advice: be sincere, helpful and get involved.
