Probably at some point in the future but you may be waiting a long time for incomes to catch up to support those prices. 

does anyone know of a minimum purchase price rule to buy investment properties in Pennsylvania.

They have a lot of power (and perhaps overstep it as well), so it will be hard to work around their rules.

Close family and friends think we are crazy and not supportive so we are very glad to be part of the BP family!

In the meantime, my short term goal is to own 2 properties (multi family, that meet the ~2% rule - more specifics to come) by the end of 2019. 

Using the retail/MF example, to determine the value of the land for each element, you would need to figure out how many sq. ft. of what type of retail, which would define the land value (per acre or square foot) that could be supported which will be determined by the rents that would be generated against their capitalized value.

Door Hangers work my Dad did this in the 60s and 70s he bought his own printing press and guess who ran it after school.then he would go down to the salivation army Sat morn at 6 am and pick up those exiting the facility.. these guys would put out about 500 flyers a day for 20 bucks.. you could do it with highschool kids today. he put out 20,000 a week.. and then the 1% rule followed  200 leads  then 20 sales..

Is there an industry rule of thumb?

Will I be held to the same "10 loan" rule.

The court eventually ruled in his favor.
