The property will then be owned by me and my two siblings, one of whom is married to the gentleman who wants to rent the building.

and I fix it myself myself.I only recommend this for people who have the time to do it, are handy, and are not afraid of the possibility that a defective light switch could result in adopting a kitten or checking a fence for evil paper wasps could obligate a sibling to adopting a evil Malaysian Tokay Gecko that was not evil enough to deserve death from an unusually cold Florida winter.Being a landlord has had a few completely unexpected consequences lol.

If you have siblings, I wouldn't do this unless you get the property into your name. 

This will be especially useful if they decide later to ask permission for another family member to be added to the lease (sibling, nephew, elderly parent, etc) and you have already set the standard that everyone will be need to have a background check.

Him and the other 3 siblings are ready to sell.

Siblings are not involved, and have no interest in the property. 

I also have 3 younger siblings that look up to me, so I want to be proof that we can do anything we put your minds to. 

It was purchased 13 years ago for $150k.A sibling is receiving a commercial property. 

Hello My siblings and I have recently taken over our grandparents 4 family home.

You and your husband and your siblings need to seriously look at how you are going to support your parents going forward.
