Both A and B are multi family apartment buildings.The properties are worth around 1.5-2m.I wish to keep A but sell B; preferably in a tax-deferred manner.A is in an area that has been rezoned and I wish to tear down and rebuild the property as the current building is old and I can get more than 4x the square footage because of the new zoning changes.Is it possible to sell B and use all of the proceeds to fund the development of A in a tax-deferred manner?

Ideally, I would want to house hack my first deal so that I can live rent free.If anyone can recommend me to some realtors I would greatly appreciate it! 

I have previously sold properties in this town, but have not found an ideal summer/beach rental and student rental until this deal presented itself.  

Me and my wife have developed our real estate business the last 4 years and I really wanna streamline it to where we really happy with it and have freedom.

Ideally you want to buy 70% of ARV ($108K) or up to 80% ARV ($124K), less repairs in both instances. 

The owners are older couple who would really like monthly income and to sell to us (we've developed a good but fast relationship with them). 1.4M sell price, 4% interest locked in and amortized for 25 maybe 30yrs.

In an ideal world these investors would be competing against one another for your project.

Also, ideally spending some time there and getting idea of what makes what valueable in the area helps as well.

Part of it is how I present it to my parents as well and that would be a much more expensive development project than one house for myself and them.

I live in a development where there is a ton of house rehabbing taking place just don't know where to start!
