I did a similar project to yours last year and it cost me 6.5k to put in a 4 zone system+ vents into bathrooms.Price out your system online, find installers willing to quote you a labor only price.

You can also check their reviews online at Google, Facebook, or Yelp.

Keeping your mind open is one of the best practices in life.Having said that,  I find myself always questioning interesting points and theorizing on real estate success. 

Just started my online RECP today.

I looked up the info on the property online and found out that the property is a rental and the owners are out of state.

@Jim Froehlich The whole mantra of "find a good deal and the money will follow" is either said by newbies (because they read something online) or gurus who want you to pony up the cash to buy their program. 

Which means, if your RI business partner is going to be paying the mortgage, you should have some way of periodically checking that the payments are actually being made on time (for example, online access to the account if it's an institutional lender).After all, regardless of whether it shows up on your credit report, you'll likely be personally guaranteeing the whole amount of the loan which means if your business partner dies or walks away, you could be responsible for the entire loan.

Look up their online reviews, what area they specialize etc... in most states you need to work under the supervision of a Broker for a specified time frame before you can take your brokers exam and open your own brokerage

I know the practical experience is better than any degree but I would like to obtain knowledge practically and theoretically

I would ask them where do they practice in any particular area in town and why?
