It's more important then ever to understand your financing options. In light of all the changes in the banking and mortgage industries, it is now equally important that WHAT you are buying is a "qualified" property, as well as your financial ability to buy that property.
If you are looking at property that is held in a condominium regime, it is essential that the entire building, and their Rules, Regulations, By Laws, etc. have been approved by the lender. Most lenders will sell the loans they make on the secondary mortgage market (Fannie Mae, Freddie Mac), and if the condominium documents have not been reviewed and approved, lenders will deny these loans based on the building, and not the credit worthiness of the borrower.
You need to work with an agent who understands the condominium market, and who can assist you with your financing. Many buyers have found they have gotten very deep into the buying process, to later learn that they can not obtain the loan they were looking for due to the condominium regime and how their By-Laws were written.
In Ocean City, Maryland, there is a list of pre-approved buildings that will meet Fannie and Freddie guidelines. That doesn't mean that you can not get a loan in a building that is not on the list, however, you need to work with someone who knows how to make that loan work.
Can you elaborate a little more? I have lost several deals on condos with too high of an investor ratio in the past. I know they just changed the criteria for 1st time home buyers and 2nd homes but what about investors? How do you "make the loan work" for them. If the ratio is over 49% who wants to do these mortgages?
