But I generally ask for property details, (the appraisal districts in my area are often incorrect on the # beds/baths etc).

If the neighborhood looked well groomed, houses have nice curb appeal, decent school district then it's looking good.

Most families would like to be settled in their home/rental/new school district prior to school starting.

That said, it is not in a historic district so it will not be subject to their regulations if I need to deviate somewhere. 

Does anyone know of a wholesaler in the DC area that can find a SFH in good school districts in Northern Virginia (even as far out as Warrenton, VA) for under $450k that need light to moderate rehab?  

This seems wrong because the situation seems ideal for conversion to a rental: we bought in 2010 in the middle of the housing trough (low expenses), purchase and rental markets are really hot in our area, we are in one of the top elementary school districts in the city, etc (high revenues).  

They don't have a good school district or a histortically good reptutation to hold on to.

Some appraisal districts have gone completely off their rockers and decided to do whatever they please disregarding what the property is worth and what it can be actually sold for. 

There are lots of towns in CT with median home prices well over 300k and awesome school districts (for locals, think West Hartford, Farmington, Orange, Monroe) where you can pick up a scraggler for 150-200k, give it some minor/straightforward rehab (usually kitchen & bath updating, a new face, and just a lot of lipstick) for under 50k, and all of its comps are selling for 350k+. 

The house is situated on a downward slope with a small creek running beside the house (I wonder if this has contributed to any foundation issues) Great neighborhood and school district.
