What is considered a "healthy" level of reserves for a condo? Is

Hello:

I am new to home buying, and thought perhaps a few of you could give
me some perspective.

I am trying to buy a 1300 sq ft condo in NAshville TN.  It is selling
for 195K.  They currently pay 121 per month in association fees, but
it is "expected to go up" to about 150-175 per month is all I have
been told, but with no explanation.

I am curious to know what would be considered a healthy level of
reserves for the association??? The roofs look fine, and the units
were built in 1986. Is there a standard amount per unit that they
should have.

Also, how "normal" is it for an interested buyer to be told from the
seller that the financial statements are not available unless an offer
is made?

Thanks for any comments you can provide.
