You can buy a house with an offer written on a table napkin.

Provide things like colanders, mixing bowls, spices, salt/pepper, napkins, knife set, cutting boards, measure cups, spoons, blender, wine glasses, wine opener, pizza cutter, etc.

Doesn't even pass the napkin test.

This was due to the concrete and the type of foundation and floor slab - this basement had what is called a monolithic pour and that can result in thicker areas for the jackhammer crew.I have been able to find prices below $100 per linear foot of perimeter, so I think his projected prices might be high - at least for SE PA.Now, if the property is inside the City of Philadelphia, this water could be due to how the storm drain and sanitary sewer system in Philadelphia are one and the same, not separate systems.

In my state, you can literally write a contract on a napkin, if you like. 

Do you have sanitary sewer or septic tank? 

I developed a back of the napkin type excel model which allows you to change various inputs (purchase price, HOA fees, down payment, PITI, what your rent would be, etc.) and determine if, long term, it is better to rent or to buy the condo.PM me and I will get you that spreadsheet!

Water/Storm/Electrical/ sanitary?

With that said, we have started to learn how to use the multifamily underwriting spreadsheets including the "napkin" underwriting spreadsheets. 

If you are looking for something to fill your day again, you should get a small notebook (only use it for this) and whenever you have free space in your day pull up a market on Zillow and start analyzing every single family house listed for sale that is in your price range and run napkin investment numbers on it to determine how it would perform as an investment property based solely off of the info that you can find online.
