At some point you should have achieved those BIGGERpockets that will now enable you to use your own cash to invest.The housing market is doing well now. 

Your money is growing at 100% per year and you could (again, theoretically) just keep adding more capital to enable he team to do more flips:  Year 1: $60KYear 2: $120KYear 3: $240K Year 4: $460KYear 5: $920KYear 6: $1.8MMSo let's take this extrapolation and create a better marketing pitch:"INVEST $30K WITH ME AND WE WILL RETURN NEARLY $2 MILLION DOLLARS TO YOU AT THE END OF 6 YEARS!"

If you just want a half a dozen free-and-clear rental properties to supplement your retirement income, then pay them off (especially if deals are hard to come by or the numbers don't make sense).There are many people on BP that haven't been in the real estate game long enough to have weathered the 2007-2008 storm with substantial real estate holdings, so be leery of taking advice from these people when it comes to risk and leverage.  

The guys who want to retire; they aren't in a hurry to sell/not desperate, but like not having to pay a Realtor, AND they are interested in seller financing to supplement their income.

There is zero logic in supplementing any tenants rent out of your own pocket.

My guess on the deal you're referencing would be that there's a 6% pref with a 2% accrued/catch up, in which case the accrued would be caught up during an equity event - refinance, supplemental loan or yes, the sale of the property - for a total of 8%.

Here is some good supplemental information:http://www.leadsafeillinois.org/owners/http://www.leadsafeillinois.org/tenants/

I agree that I should do manual research and use airdna as a supplemental info source.

At 59 you can look at investing for supplemental cash flow. 

At 33 years old my wife and I have decided to look into building up a real estate portfolio to help supplement and possibly bring about sooner my retirement.Just to be clear I am very happy in my career and am not looking to quit my job.
