I have the mental and physical ability to build more, just not the finances... 

For example FHA guidelines say you can deny an ESA if they cause an undue financial burden, cause a direct threat to the health and safety of others (the letter from the neighbor supports this), or cause substantial physical damage to the property.

Brought all parties together and physically helped my friend go through the house to pack up family heirlooms What was the outcome?

I mean, as a building, they are probably the easiest to physically expand, are you also pouring a slab?

Is it 83% physically occupied, or economically occupied?

@Srinath Gopinathan, I'm sure you can physically go to the assessor's office and get this information.

I would like to know which physical areas I should focus on. 

They might give them to you before to make sure that you actually perform a physical inspection so that contingency would be removed from the offer.

If you don't want to physically be there, look into Showami.

You can 1031 exchange out of a dst into a physical property when the properties sell.
