I really want to get a good grasp of this stuff before I start throwing real money at it. 

We haven't had anyone leave yet and everyone seems happy that we didn't come in and 'throw' everyone out.

Not a great house, but not a bad house.Was thinking of throwing an offer out there, but I don't know if the potential issues outweigh the numbers, etc.Any thoughts?  

Anyone with an ounce of brains will throw that straight in the trash.

Ive been approached by a tax firm telling me they have a 90% success rate at lowering property taxes in Travis and Williamson counties which is in Austin, TX.Im really intrigued by this and may proceed but thought i'd throw some concerns on here first.My concerns are:1) the fee they charge which is"Consultant shall be paid 40% of the value of actual tax savings to Client resulting from Consultant’s efforts.

I don't run around tweaking and throwing down money on crappy deals.  

Second: Does your letter look like junk mail that people would just throw away without opening? 

They aren't all your target audience.

This is throwing my plans off because I do not have that much equity in the property to pull much out at 70%.

It may cost you $250 but you can also get a letter from an attorney, if you throw a big enough stink they usually drop it with no problem because they want to get their commission and don't want to lose the sale, because realistically if you push it you could put a lis pending "legal action pending" on the property and no one could sell it until the legal issue is settled in court which could take a year.
