Ductwors is shared as the house is currently a single family home.I will be tearing all many interior walls and all the ceiling between the first and second floor units for sound proofing and fire-proofing.I figured a High velocity system would work if I stuffed 1 unit in the basement and another in the attic.

You submit pictures of the fix as proof.

Hello all,Was curious if anyone has come across a collection(s) of real estate transaction case studies (Preferably residential)? 

.- submitting proof of funds with your offer (i.e. bank statements)- including as few contingencies as possible on the offer/contract (i.e. inspection, appraisal)- purchasing the property 'as-is'.

Supposedly current on rent according to the spreadsheets the sellers agent sent me.The house had a fire in the attic before the previous owner ever bought it, so some of the wood there is charred.The concerns are:-Do I trust their spreadsheet as proof the tenants are current on rent?

You have posted in a public forum so it can be used for proof.

I took this around yesterday when collecting rent. 

If you want to be taxed in a different state, have proof you actually relocated. 

Or do I just need to focus on making it bomb-proof and planning on them destroying everything so don't make it nicer? 

Just be aware that your offer needs a proof of funds letter from the bank.
