I'd say the cheapest and first thing you should do is speak to your local insurance agent and get a break down of what your limits are and what is covered on all your insurable assets, i.e. vehicle, properties, E+O if applicable etc.

Increased fees for vehicle registrations in business name3.

At least with a loan you don't get the 10% and of course you pay back the loan with interest but you are paying yourself that interest.I'd really think twice before withdrawing your 401k or any other retirement vehicle.

I am studying precisely to do what you mention.

In this market, if the payments are made in a timely fashion the odds of that lender initiating a call are precisely zero.

Whereas real estate you get in and influence the value of the investment directly by improvements and such, and you decide what direction the investment is going to take.They are both very interesting and I think a person's personality comes into play as to which vehicle they prefer, however in the "long run" they both done well for investors!

Now an athlete may do this when he is retired, but that is only because they can no longer make any money competing in the sport.This comparison may not be precisely apples to apples, but I think it gets to my point.

With your $60,000 - $90,000, I would pay off your student loan debt, buy the wife a vehicle with cash.

1) You get the cash flow now instead of having to wait til retirement - at which time you'll have to pay taxes on it when you pull it out.2) You can leverage that money to buy more properties.3) Real estate income is pretty much tax free anyway so what do you really gain by leaving it in a tax free vehicle that is only temporarily tax free - you'll pay when you end up pulling that real estate out of the 401k. example with some VERY loose guestimates on the numbers:100k buys you one house (worth about 130k) free and clear in your 401k.

Will and John, are you suggesting opening a Solo 401k and staying away from the sdIRA entirely, or doing both with different investing goals for each vehicle?
