Get constrc loan to rebuild if you have an equity loan on propty

[Dawn Gawron]

We have an apt building in Chicago that is older and that has one apartment gutted but we found out there is a water issue and foundation. We only have a Equity amount of 48500, Is there a mortgage company that can roll our existing equity loan into a construction loan to tear down this building and rebuild. There are 12 brand new town homes across the alley going up. Can anyone refer me to someone and/or give advice?
