I think of flipping as flipping my cash, the property is just the vehicle, and the strategy is the fuel.

We are also pretty passionate about real estate investing and enjoy the process.At this point, is it worth opening and starting to invest in the Roth IRA vehicle?

I do see real estate as an income vehicle for a 67 year old that was not able to build on her retirement.

Proper brick storage units with secure locks could provide shelter for crops, vehicles, furniture, machinery and anything else that needs to be kept while rebuilding happens.

That is the "secret" to true wealth.The truth is, there are no "secrets" to RE investing, only education and experience.There is no question that RE is one of the greatest investment vehicles to wealth and income along the way.

She has already lost one home and a vehicle.

Real estate can be a great vehicle to generate passive income and wealth, even buying just one SFH every year.There are also other options to leverage your time and resources more effectively and retire earlier than 15-20 years, depending on your criterion for retirement.It seems like the faster path to retirement is to treat your real estate investing as a business. 

I agree about the blood...and the debt after retirement...which is why I mentioned NNN as the vehicle. 

I borrowed the money to buy this house from bank using my vehicles as collateral.

I’d find the motivation when you interview for the privilege of helping them with their situation through the vehicle of real estate.
