I currently am working in the scrap metal industry in a job I love, but 6 days a week and usually almost 70 hours a week doesn't leave much time at the end of the week.  

@Roman RytovIndustrial buildings in the southeast is the only class I invest in.Is it a pre-engineered metal building or block and bar joist type structure?

don't know if stakes are included or not (metal or wood?)

Also take a look at the solo 401k.Following are the similarities and differences between the solo 401k and the self-directed IRA.The Self-Directed IRA and Solo 401k Similarities Both were created by congress for individuals to save for retirement;Both may be invested in alternative investments such as real estate, precious metals tax liens, promissory notes, private company shares, and stocks and mutual funds, to name a few;Both allow for Roth contributions;Both are subject to prohibited transaction rules;Both are subject to federal taxes at time of distribution;Both allow for checkbook control for placing alternative investments;Both may be invested in annuities;Both are protected from creditors;Both allow for nondeductible contributions; andBoth are prohibited from investing in assets listed under I.R.C. 408(m).The Self-Directed IRA and Solo 401k DifferencesIn order to open a solo 401k, self-employment, whether on a part-time or full-time basis, is required;To open a self-directed IRA, self-employment income is not required;In order to gain IRA checkbook control over the self-directed IRA funds, a limited liability company  (IRA LLC) must be utilized;The solo 401k allows for checkbook control from the onset;The solo 401k allows for personal loan known as a solo 401k loan;It is prohibited to borrow from your IRA;The Solo 401k may be invested in life insurance;The self-directed IRA may not be invested in life insurance;The solo 401k allow for high contribution amounts (for 2016, the solo 401k contribution limit is $53,000, whereas the self-directed IRA contribution limit is $5,500);The solo 401k business owner can serve as trustee of the solo 401k;The self-directed IRA participant/owner may not serve as trustee or custodian of her IRA; instead, a trust company or bank institution is required;When distributions commence from the solo 401k a mandatory 20% of federal taxes must be withheld from each distribution and submitted electronically to the IRS by the 15th of the month following the date of each distribution;Rollovers and/or transfers from IRAs or qualified plans (e.g., former employer 401k) to a solo 401k are not reported on Form 5498, but rather on Form 5500-EZ, but only if the air market value of the solo 401k exceeds $250K as of the end of the plan year (generally 12/31);When funds are rolled over or transferred from an IRA or 401k to a self-directed IRA, the amount deposited into the self-directed IRA is reported on Form 5498 by the receiving self-directed IRA custodian by May of the year following the rollover/transfer.Rollovers (provided the 60 day rollover window is satisfied) from an IRA to a Solo 401k or self-directed IRA are reported on lines 15a and 15b of Form 1040;Pre-tax IRA contributions on reported on line 32 of Form 1040;Pre-tax solo 401k contributions are reported on line 28 of Form 1040;Roth solo 401k funds are subject to RMDs;A Roth 401k may be transferred to a Roth IRA (Note that from a planning perspective, it may be advantageous to transfer Roth Solo 401k funds to a Roth IRA before turning age 70 ½ in order to escape the Roth RMD requirement applicable to Roth 401k contributions including Roth Solo 401k contributions and earnings.)

I have a great roofer if you need one who could save you on cost for a metal roof.

Assume you sleep 8, 2 for hygiene and bodily actions, a regular 8 hour job, leaves you with a total of 6 hours of "free" time; which then you must subtract every other part of your day; commuting, grocery shopping, laundry, etc.Now if you can use those 6 hours to make money that you would otherwise save, it make sense.Here is some good info from somewhere else (in 2013):"It's Literally Not Worth His Time to Pick Up a Dropped $100 Bill From the Ground.

Then somebody came and got all the metal for scrap/recycling. 

Depends on regulations, you might get by with a metal building and gravel lots.Really, without more information about the location, town, highway access and terrain, we are shooting in the dark

Also, I'd take down the metal awnings, get a nice front door and add some key landscape elements to balance out the front.

Are lenders opposed to lending on post frame/pole barn style metal residential buildings?
