Our Lakehouse neighbors drain their hot water tanks & try to blow out the lines with compressed air.

With most of the stock being older properties built ~1900 - if the property was not kept up with you'll run into a number of old things such as....knob and tube, lead paint, asbestos wrapped piping.

Wonder if anyone would have any idea of cost to change out and update Knob-and-tube wiring in Easton, PA.

Have the electrical panels been updated or does it have the original knob and tube wiring?

Make sure to check with your property insurance to see if you would somehow get dropped from coverage if you knowingly let Tennants start an air B&B in your unit.

An air conditioner will eat 3 months of your rent.

I have covers on the thermostats but the tenants find ways to get in them and raise heat and lower air conditioning in the summer.

It will only get better as the Metro Air Park ramps up.   

Those cap rates tend to be in the 6's.7 plus caps with new lease are in weak suburban to rural areas and cheap construction.Only time I like Dollar General with cheap construction is if in area strong suburban to urban core at low price where dirt it sits on is really valuable for future redevelopment and potential air rights.If it is sitting in weak suburban to rural area without the tenant occupying it is almost worthless.WHY do buyers buy tons of this trash then?

I would also recommend taking a look at Sky Ranch and the Transport project which is located around the Colorado Air and Space Port.
