Plumping and the heating system were nonoperational, which didn't manifest until after tenants moved in.

I was wondering if anyone else has had to replace their furnaces in 1/1 or similar size (700-1000sqft) and if there is a better heating solution that a full size furnace.

As for the unit freezing up; I am a HVAC contractor and if the unit is installed with a blower size that matches the evaporator coil the unit will never freeze up.

Walked around the outside and it looks like other 3-families in the area that, like every new building, need 5k of work.My plan is to make an offer assuming a long eviction, lots of renovation and new appliances and heating units. 

Contact me if there is a problem with the heat, electric, plumbing or roof.

For the vacant properties in the dead of winter in pa should you winterize them or keep heat on?

I found a 5 bedroom 1 1/2 bath large single family near my local college for 145k could easily rent out each room for $550x5 to college kids, worse comps are going for 180-280k it doesn't need anything but removing the okish wallpaper and a bit of cleanup and paint maybe 5k total, has tenents already in it (don't know how much there paying) so ~155k total with fees, and cost $1,650 conservatively a month water heating insurance maintenance internet (collage kids), I can't get the loan right now/don't have the time, would this be a good deal for someone to buy?

@Paul Gallardo Would probably get the most bang for your buck by updating the flooring to something like vinyl planking, updating the kitchen appliances, and as you mentioned looking to update/upgrade the heating system throughout the house. 

I have a condo that also has a little heated storage unit immediately next door.  

Throw in 30% PM fee and makes no more sense.i forgot above, LTR pay heat, power, wifi.
