I'm looking to learn the ins and outs of the business and to decide if this is a viable path to supplement (and possibly replace) my full time job as an operations manager for FedEx Ground. 

My background is in Human Resources and Payroll Accounting and my degree is in Business Management.Teaming up with a dear friend, I started REI training with mentorship, supplemental resources and technical support.

I'm looking to get into real estate part time (lending, flipping) - I have previous experience on the assessment/tax side of the industry and will be getting a real estate license to supplement my education and get MLS access.My current goal is to run through a single flip and break even.

This allowed me to verify that the door being closed in the common area, with the furnace running, would be enough to prevent the pipes from freezing.However, the Tenant has turned the thermostat all the way down, but still on, and I believe is still using the space heaters to supplement. 

Goal is buy and hold. something that will supplement me in retirement/keep me busy when I retire at 49.

Supplementing with some short term income is a good way to make those payments.    

My long term goal is to supplement my teacher's salary with passive income to the point that my sweet wife doesn't have to work anymore.

It's also more cash than I have available so I would have to supplement with a HELOC or refinance.

Have to admit some of the investing terms get overwhelming, but supplementing the reading with youtube videos of "what is ROI?" 

Our plan, and strategy, is to begin our REI portfolio now (or very soon), so that in 10 years we use REI to supplement my retirement pension and in theory, be financially free.Like I mentioned to @Eric Jones, OOS investing in a more passive manner makes the most sense for us now.
