also, there is a extra column "bankruptcy" , some of the properties marked " BK Hold" whereas some didn't. for this particular one, it didn't marked " BK Hold". when I looked up this property online, most of the websites said its off market.

Should I sell my rental to put extra money down on my own house?

You’re already paying it so it wouldn’t cost extra.

So now i have just added 2 to 4 weeks extra to a job due to delays beyond out control.

Many of the sellers dont want the extra fees I am not sure how to properly handle this.

Or we could just save the extra money & headaches and just flip the properties for $460,000+ (and our broker has not missed yet on comps anywhere in North NJ) and make a good 6-figure spread.

I’m wondering the model these agents are trying to emulate and charge for... in what way are they adding value to earn that extra 4.5%?

Personally I am trying to become financially independent and am willing to take on some extra work and risk to reach it.  

@Robert Burns That's just how it goes.

You will only get burned, regardless of how sneaky or right you think you're being.
