1st rental property in very bad shape.

[Brad Armel]

I recently inherited a house in Daytona beach that is 884sq ft, wooden frame, with a leaking roof, rotting wood frame and T1-11, the floors are sagging pretty dramatically as well. I initially thought I could reframe the foundation and rebuild up (walls, windows, doors, ceiling, roof) the more I analyze the project the more confused I get about the direction to go. Pour a slab, modular home, or just stick with the wood frame foundation idea? I know modular homes don't add any real long term value and our goal is to make this and rental property we can hold long term. This is our first rental property and being confident in a direction would make this whole process much easier. Any advise would be much appreciated. Thanks.
