My wife and I have completed a 1031 exchange of a property we owned in joint title. 

The RE broker found someone reputable and got back to me with a quote of $45K for the big office building and 40K for the smaller office building (would need to be done in next 3 years) – this would include tear down, using shingles that last 30 years, repairing mortar joints on chimney, etc.

Have you thought about partnering up in joint ventures or getting involved in syndication?

(Jointly we make 90k/year)2.

(jointly we make 90k/year)2.

For example if you find a motivated seller you can joint venture with a person to bring in the money and split the proceeds. 

I am looking to convert that into full time rental property and also I want to void paying the Capital Gains Tax (500K for Married filing jointly), I have considerable equity in the home, I don't want to sell the property to others now and want to hold it for few more years.From the Article below by @Brandon Hall, I see that I can sell this SFH to an LLC I own.

Consider Joint Ventures, You lend your credit profile and operations experience if needed, in exchange you get a fee + % of profit over a certain amount.

I provide one when I work with someone on a Joint Venture.

Or if you run into a wholesaler while do that you could always JV or joint venture with them assuming that they have buyers.
