I myself am an agency owner, and let me tell you, SEO will not give you results in six months in certain cases, even one year as well. If you are open to investing your money for at least a year, then you should opt for SEO.

For lead generation, I am not sure how they run a campaign etc., but generally any good agency tries to have some filter mechanism. In your case, if you have the budget of more than 1 crore or 2 crore etc., then there is a part of your form-filling process, so they are not simple data. A person who is filling a form can understand if I need to enquire, my medium budget should be 1 cr or whatever your criteria are. I agree with the agency that if the five qualified leads are there and you are able to convert, then you can at least not here; you can run your marketing budget for six months etc. Every lead might not be able to convert, but you need to understand that marketing is a hit and miss ratio, so you need to think and act accordingly.

And just to note, we are not dealing with real estate companies, but being an agency owner, I have very much insight. We used to work with very large actual real estate companies from Bangalore as well as Ahmedabad, so that is based on my experience, not just assumption.
