But those estimates would be from un proven vendors .    

But the good news is that you can recognize what they are saying and learn from that to improve yourself.

So if you were to use a Fannie/Freddie loan (if you recognize those names) they have ALL SORTS of rules when it comes to buying a home with cash. 

If this too is a lost cause, like househacking is, you'd better take real estate off the table as a lever to pull to get you to financial independence.There seem to be a number of obstacles standing between you and the well-known, proven paths to FI that begin and end with the woman you want to take along with you on this journey.

Any advise for me as far as which methods have been proven most effective for your business when it comes to generating leads, post cards, cold calls, etc.

@Elena MaflaYou will have to recognize some of the gain.

.)● Gain included = (Reinvested amount - basis increase) = 1M - 100,000= $900,000.If A also sells the investment in QO Fund in Dec 1 2031, 10 years later, he does not recognize any capital gain on the sale of his investment in QO fund.If A sells the investment before 10 years, basis in the investment is based on the time it is sold:Basis starts with Zero and increases in this order■ Held for 5 years - 10% of gain reinvested■ Held for 7 years - 15% of gain reinvestedBasis at 5 years = 100,000Basis at 7 years = 150,000Thus gain/loss is determined based on the FMV of the investment less the basis at the date of sale.

  ; )I'm going to assume you're not in the 'trade or business' of lending money, as the fact pattern laid out neither explicitly states nor suggests it.If so, as an individual you're on the cash basis method of accounting (with limited exception) and shouldn't have recognized any interest income so far.Your basis in the acquired property is your basis in the loan plus acquisition costs.Your holding period in the property begins on the date you acquired the property. 

So, the brokerage is the Unicorn you mention, but perhaps with a saddle that does not fit just quite right depending on what your needs may be.With a brokerage like Schwab or Fidelity (two of the best for this usage), they recognize the account is for a Solo 401(k), but they are not serving as the 401(k) administrator or custodian. 

Possible reduction of the amount of gain ultimately recognized through a basis adjustment; and3.
