The other two-thirds of your sale profit is taxable from the sale of your rental units.  

Account Closed,Never mind what the County think's it's taxable value (assessment) is, you need an appraisal or a CMA (Comparative Market Analysis) to determine the approximate market value of any piece of property.Real estate agents (who may or may not be Realtors(TM)) are not bankers.

@Bill Mcdonald Here are some of the similarities and differences between a self-directed IRA and a self-directed solo 401k: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 bankruptcy creditors;Both are prohibited from investing in assets listed under I.R.C. 408(m); andNeither may be directly invested in your own business startup 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 (self-directed IRA LLC) must be utilized;The solo 401k allows for checkbook control outside the LLC;The solo 401k allows for personal loan known as a solo 401k plan If you borrow from your own IRA, it will be deemed a taxable distribution;Unlike an IRA, a Solo 401k can invest in life insurance;The solo 401k allow for high contribution amounts (for 2015; 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 his or her solo 401k;The self-directed IRA participant/owner may not serve as trustee or custodian of his or her IRA; instead, a trust company or bank institution is required;Unlike an IRA, generally 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, generally 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--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 401k RMD requirement;Roth IRA funds are not subject to requirement minimum distributions (RMDs);The fair market value (FMV) of assets held in a self-directed IRA is reported on form 5498;The fair market value of assets held in a solo 401k are reported on Form 5500-EZ;At termination, the solo 401k is required to file a final Form 5500-EZ and 1099-R; andAt termination, the self-directed IRA is only required to file a form 1099-R.

For example:  (a) RMD calculations and (b) the amount of taxable income created by the distribution.

The owner could do that, but it triggers a taxable event and the funds might well be better used to retire the debts of the corporation.

Your money is made in VOLUME.That being said, I am happy with my current strategy of buying units within a taxable/cash account and buying notes within my Roth IRA.

Your net taxable income is subject the tax rates.

Almost every bank will do this loan with 20 min signature, NO credit checks, and the interest is incredibly low (normally a +3% margin from what they are paying on the deposited money, now 0.001% in most banks)Advantages: No credit reporting, Not a taxable event, great on the balance sheet for your operations and net worth, access to preferred banking private banking rates for other products, useful as a score card for returns, built in emergency margin of 10% due to the 90% LTV banks use, etc.Disadvantages: Large Liquidity needed, deposited funds at -2%+margin loss of value due to inflation (if at all), It's the absolute lowest form of leverage financing IF you happen to have $100k you can park for 18 months, why $100k and not $70k?

I have some stocks in a taxable investment account.

My taxable income is about $15,000.
