Buying lots with old single wides

[James Edwards]

I've seen a lot in town with waist high weeds/brush. I know it has been vacant for quite some time, and the homes are older. No real idea of condition on them. Given that w/s/electric hookups are in place for each do you think you would spend the time/money to fix up the single wides, pay to have them hauled off and install new? What would be your deciding factor? Limited information I know, but my thought is given construction costs these days I would probably be better served spending the money to fix them up to rent. 

ETA: If the repair time/cost is reasonable. In my mind it would cost more to have them hauled off/disposed of, and then to purchase even a used mfg home and have it hauled/setup.
