While they will fight, complain, try to talk their way out and make you hold their feet to the fire.

Just because a tenant says that they are going to fight you doesn't mean they actually will.  

I think you should look more at them as a whole profile, I know people who have been arrested and never charged because a jealous ex lover called the cops over a fight you just never know.If she has a great credit score, Landlord reference and has been gainfully employed for 3+ months and her boss gives her a good review.

It's hard for any tenant to fight that in court.

He can't fight that.

Take this as a lesson to ask for appraisal earlier in the year or fight the up hill battle against county government criminals?

I don't fight it and I don't "just move on".

Needless to say, I have been fighting that same battle.

So if it is legal to single out investors i will cave, I dont have the $ to fight them but will try to raise other investors to get this changed in my association IE. fire some of the board  

there are so many 2 family homes with all kinds of configurations there. the best you will be able to do is try and match the rest of the house, square foot, number of baths etc. you may be able to get away with a 6 bedroom house as a comp, 3 and 3. i know i am having the same trouble with a house i own in PA, its under contract but when they came back there was no exact comps to mine, we are in the process of fighting what the appraiser came up with right now, they came up with $38,000 under my list, but i know i priced it right based on price per square foot and whats in it, 2 family with 3 and and 1 bath each. try averaging what a 2 family sells for per square foot, that should give you an idea. then sell it to me for 100,000 less - just kidding, but you can let me know if you do decide to sell, I'm in the town next door.
