Luckily for me, I had 8 other pricey condos that had doubled and could well than make up for those 2 dogs.  

Here is a good summary of PA security deposit rules:https://www.thebalance.com/pennsylvania-security-d...Failure to return the deposit within the thirty days in PA is penalized by doubling the deposit.

My Dad likes to buy these types of properties and turn them into rentals to collect the extra cash flow from the non-conforming units ... double bonus if it is in an area with college rentals (that tend to rent by the room) or airbnb.

It could double, it could tank. 

now take the same city and go for a 1000.00 a month 100k rental..  3k a month is the qualifications to get into the home.. leaving 1800 a month to live on or almost double.. can you see how that works.Investor simply cause their own problems with their own greed and expectations that low rents low value assets perform exponentially to higher value assets.. and nothing could be further from the truth.. just watch the Morris videos how he explains how solid those homes are .. and If you fall for that line of thinking well you could have some issues long termListen to Chris Clothier and his thought process of being on the exact opposite end of the spectrum and U don't see his clients on BP whinning about getting all these wipe out tenant issues.

I am a newbie, but from Biggerpocket podcasts and several books I read, it seems that commercial real estate realtors (brokers) are quite different from the residential realtors: they usually let several buyers on the top of their list know their deals first before putting them on the market, so that they can have the double commissions (6% of a 2-million deal is quite different from 3% of 2 million deal).

yes  VERY VERY upsettingThis and many other reasons I almost always contact the listing agent and let them get double commission
