Purchasing Land with Home and adding rental home or duplex

[Jesse Colmenero]

I'm looking at 8 acres outside of city limits in North TX. The property has a house that I would use a primary residence.The thought is that I would then build one or two duplexes or maybe even single family homes on the land. Can anyone provide some insight on what my options would be from a financing standpoint? If we buy the property using a conventional mortgage, how would we finance the two houses/duplexes that we would build? Would everything need to be refinanced?
