Here are some factors to help you make an informed decision:SDIRA vs. e-QRP:SDIRA (Self-Directed Individual Retirement Account):Allows for a broader range of investment options, including real estate.Provides more control over investment decisions.Requires custodial services, and there may be fees associated with the SDIRA provider.Strict rules and regulations to ensure compliance with IRS guidelines.e-QRP (Enhanced Qualified Retirement Plan):Similar to a 401(k) but with enhanced features for greater flexibility.Generally, more streamlined than SDIRA with fewer administrative requirements.Allows for real estate investments, business investments, and more.May offer more control and fewer restrictions compared to SDIRA.Financing Considerations:Both SDIRA and e-QRP can be used for financing, but the terms and conditions may differ.Check with your chosen custodian or plan administrator to understand the borrowing rules and any potential penalties.Tax Implications:Understand the tax implications of using retirement funds for real estate investments.Consult with a tax professional to ensure compliance and to minimize any adverse tax consequences.Market Conditions:Consider the current real estate market conditions in the location where you plan to buy the beach house.Evaluate potential risks and rewards, especially in the context of your investment horizon.Long-Term Strategy:Since you're planning to work for another five years and potentially sell the house later, ensure that your investment aligns with your long-term financial goals.Interest Rates and Economic Conditions:Monitor interest rates and economic conditions, as they can impact the timing and profitability of your real estate investment.Professional Advice:Consult with financial advisors, tax professionals, and legal experts to get personalized advice based on your specific financial situation and goals.Due Diligence:Perform thorough due diligence on the property, renovation costs, potential rental income, and local market trends.Remember that real estate investments, especially with retirement funds, require careful planning and adherence to regulations.

Here are some of the reasons why: Compared to an IRA, Solo 401k contribution limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

When they are being picky, it is just to protect the integrity of their paper trail for the regular custodial compliance audits they undergo. 

I'm a single Dad with sole custody of both of my kids.

Some people like the custodial style and some people like the speed and ease of checkbook control.   

As a single dad with sole custody, the kids have always tagged along in some way - sometimes looking over my shoulder at the computer, sometimes riding along to look at property.

There are two potential options: 1) You can have a custodial account with one of the self-directed custodians.

There were way more custody case filings than divorce filings.
