Houses for sale under 10k will need repairs - probably heating, plumbing, bathrooms and kitchens - not to mention clean out, paint, drywall and landscaping.
Finding the property is no issue here. The managing of the rehab should be done by a licensed contractor, not a realtor. The letting (leasing) of the units should be done by a realtor. That's how I would go about it.
If you have the cash and the forethought to rehab properties across the pond, there is good money to be made. But you must be diligent in your interviewing. I know the areas that can benefit from a rehab, where some will not appreciate if you put in any money at all.
I suggest you contact some agents directly and discuss what you want out of a project. Then ask for references.
