Since I don't have enough cash in hands I decided to use money from my 403(b) retirement fund.

I just retired from the Army and lived 10 of my 20 years overseas. 

Just like bank financing.I don't have any idea why the Seller you are referring to would do Seller Financing, but since you say he is "an older gentleman" he might have retirement income, and social security that would be taxable if his other income goes over a certain amount, and he might just like the idea of not paying all of the tax on his Capital Gains in one year.In Seller Financing, the Seller reports the amount of the Down Payment plus a fractional amount of the principal portion of each note payment received in the year of sale as Capital Gains.  

If they are retired, give them a brochure for a condo in Florida (for under $200k.

Even more recently, I did thorough analysis of my retirement plan, and I realized it's not going to get me to where I want to be. 

All i know is everyone around me is using real estate to acquire wealth achieve financial freedom & retire early ...I'm ready to do all 3.Anyway greetings to all hope your having super fabulous & productive week :)

welcome @Jason SperlingI wouldn't touch your retirement accounts.

Hi - I was wondering if you were using a brrrr strategy on all the properties you bought how do you go about paying it off and retire early?

I too want to retire one day with passive income and know that finding my own investments will be a key to that end.

these are just a few.Do they have all of the security depositsLook at least 2-3 years of P & L statementsHas this owner that is retiring been involved daily and holding the owners hands, or does he have a staff to handle day to day?
