The three most important things to consider when purchasing real estate are location, location, location!
Weeds should not be a concern, I would think any landscaper would cut them down for a fee. As far as the pool goes, as Joe said, check it out with the NYC Dept of Buildings 718-816-2315

Weeds are not a big problem. you can have a loan maintnance company take care of that or in some cases you can even have the company that will install the pool for you agree to clean it out. Hope this will ease your mind.
