@Chirag Mehta For construction costs, you should be around +/- $100 PSF which would include all sitework, utilities, and going vertical with modern finishes.  

I think there are two maybe 3 ways to look at this in my mind.  1) you go into it and bring it all up to modern standards but using that old charm to basically take what is there bring it up to modern standards and rent it out essentially I'm thinking cocktail bar or something trendy like that.2) most banks are on really good centrally located real estate if this is true, then I'd consider it for the dirt, plan to scrape the lot and go vertical with whatever the highest and best use is.3) a kind of combo of the two, if the lot is in a good location and its doable, pull the vaults or other "character pieces" out of the building, scrape the lot, and build whatever is best suited for the site there, but incorporate those historical pieces into the final designs.Is the site near a major retail area? 

The good thing is the duplex is worth almost double what we built it for and we have had good tenants on both sides ($185,000 rental income so far) except for the bed bug lady so everything has worked out ok. 

Hi, what’s the young lady name?

He met a lady from Mexico that could not even speak English.

I only hold decent properties in nice areas, modern construction, etc.

Their members do the same thing this lady is doing, look for scammers. 

I usually recommend clients a pretty easy cosmetic rehab which is refinish floors, replace cabinets with modern white ones, add a white stone, new appliances, new bathroom vanity/mirror/light fixture and add in unit laundry. 

Left some of the character while adding modern amenities, brought it up to code, and staged it.

It had about 40 something people in there and and at least 36 of them was signing up... me,my wife, and a lady I met at the event walked out....pure scam
