Many new builds in philly, if you'll notice, MOST of them have a drain line right in front of the property (collects water from roof via gutters, and drains in front of building because that runs into main sewer lines). 

What will the R-factor change be with the additional insulation?

Is mentoring his main source of income? 

@Brian Erickson The main benefit of having a license is access to the MLS for the purpose of doing comps (comparable sales).

Those numbers will help in factoring that cost of money into my deals to hopefully avoid failure altogether!

Also heard good things about NC raleigh/ SC columbus areas.Would be looking at his 3rd property - mainly condos, multifamilies in the 100-300k range - or just paying off all current debt. 

One of the main reasons why I want to do real estate is because after losing my job last because to a merger, I wanted to have another way to provide for my family and to reach financial independence one day.My goal is to become a buy and hold investor, buying duplexes and multi-families in my area and possibly out of state. 

This leaves very little window for an effective "Subject To" deal.The other factor to consider is that mortgage arrears (historically <1%) and defaults (historically <0.5% ... less than 0.3% in parts of the country) are substantially less than in the U.S.A.  

Definitely consult a lawyer about the situation and make sure what you’re buying has this factor priced in.

If its an occupied property you need to factor in eviction costs/time and you will likely have no interior access so rehab costs are a complete unknown.
