Rollover funds from your employer 401(k) if you want to use those for investing.

Are you working with a reputable firm to establish the Rollover As Business Startup structure?  

Self-direct IRA: you can also roll over your 401(k) into a self-direct IRA by choosing the real estate as your investing option.

Basically you can rollover your existing Roth IRA into self-directed Roth and then invest in real estate inside of your account. 

Roger- I'm no expert on solo 401(k)s but I imagine you'd need to roll over your 401(k) to a self directed IRA to invest in real estate.

If you choose to roll over, it might compound your gains over time.

I had kind of resigned myself to being able to roll over a few of the highest value ones into a commercial property and just eating the taxes on the rest of them.  

If you reinvest your money, there is no rollover of funds.

Yep a common trap is thinking you will be the landlord that understands them and gets them paying where others couldn't.Then you start learning a very expensive lesson after you have been taken advantage of many times.My goal when working with tenants is under no circumstance could past rent roll over to the next month.So if rent was 800 and they had 600 and said in 10 days they would have 200 more and then ignore me or give a sob story I file eviction.

I understand that I cannot contribute more than I earn, but what about rollovers?
