If you need your land surveyed (boundaries marked), I can recommend good land surveyors local to you as well.

I signed up for an annual membership over a year ago, and after attending 3 or 4 monthly meetings I observed many of the same things Mike did.  

Consider, the new FINRA survey that identifies Americans ability to manage their finances...1.Making Ends Meet.Nearly half of survey respondents reported facing difficulties in covering monthly expenses and paying bills.2.

Like mentioned above...get a pro membership and learn how to use the calculators here.  

I just did a manual mailing of high equty over 50 and low equity lists pulled from Clothiers service that I have a life time membership.  

Planning to sign up for membership and i was wondering should i sign up for annual or monthly service.

You can also join COREE, there is a membership fee and it is part of the national REIA.

It is also currently one lot so it would have to be designed and surveyed along with a biologists survey report.

Especially since Costar bought out Loopnet they have gone up like crazy on what they charge brokers and agents for a membership.
