If I can draw them does it have to be on some special software or simple hand and ruler drawing with measurements? 

I've always viewed this property as my safety net (I grew up poor and never want my family to fall on tough times).

I've learned over the years that "how I'm feeling" isn't always an accurate measure of how things are.

What I measured was drastically different than what was listed in SDAT.

Regarding syndications, if you are an accredited investor, you can buy into $50-125M projects with as little as $100,000 and diversify for some added safety.

That seems like exactly the same thing, but with more safety for the seller.

Further if there is an event, the quicker lives are evacuated to safety and the fire is out the better - period. 

In the basement the floor-to-ceiling measurements are 6'10", 2" below the 7' minimum requirement.

@Brandon WhiteThe illegal rental unit situation Mike is referring to is typically brought about by a property not adhering to fire code, and/or rental licencing standards.In London you're required to have a fire safety inspection of the property before you're able to get a rental licence from the city.Example: You purchase a decent duplex, but when you go to get a rental licence for the property you fail the fire inspection.

Some assumptions made on the spreadsheet: property tax is 1.5% of property value, PMI is .5% of property value (I usually leave it in my calculations even if the down payment is 20%, additional conservative safety cushion :P), Agent commission 3%, vacancy 7%, capex 7%.
