No proper feed back from home loans department

We app**** for a joint home loan and received a declined letter. I enquired about how much we qualify for and did not receive proper feed back and so we app**** for a lower amount and received after 10 days was advised that the application is declined due to insufficient cash flow(do not know what this means). All we want to know if I do not qualify for the amount that we apply for how much do we qualify for. I do not think they understand what it means when they give proper feed back. If they are saying that we do not qualify then they should tell me where the problem is so that we can fix it or give you another offer. We do not want to be left hanging, we want to know where to go from here. We do not mind making 20 applications to get the desired results.
