Ok here is the deal!

Bought a dilapidated mobile home with a 720 square foot addition on a slab foundation for $4K. I knew when purchasing I would have to rebuild the mobile home. However, after further inspection I will also have to rebuild the addition as well. My options are as follows. 1) Reframe and rebuild both and have a 4BR 2BA. 2) Just rebuild addition and make it a 2BR 1BA. 3) Purchase another used mobile home and place that on the lot. The difference in cost is between $12-15K. Which would you do and why? The rent difference between the 2 & 4 bedrooms is between $200-300/month. I am going to hold onto it long term.
