Things that require security like this add financial risk because construction is like herding cats, And can be filled with time delays that mount up .This is something a more experienced operator might have known to look for, but still read and notate every contract before signing.Good Luck!

If you mount the new beam below the ceiling $1500 material labor...if you put it up into the floor joists above $2500-3000 (meaning so you can't see the new beam once the ceiling on the drywall is repaired)  Figure another $65-70 per sheet of drywall needed for repairs. 

I'm a Manhattan resident and looking to get started finding motivated sellers in Westchester county (Yonkers/ Mount Vernon area).

Mount them higher in the wall out of reach from kids and thieves.

There are literally gas space heaters mounted to the walls that require you to light them much like you would a stove.

@David Mount I don't have any experiences with turn key, but I do see the offerings.I've seen 1.5% but they are all in "c- or D areas.I have not seen any turn key properties in B areas, you can get 1.5% if you do the rehab yourself.I feel like those type of deals are kept in house.

In that case I would purchase four window style air conditioner/heaters to mount into two of the windows per unit.That means each apartment will have two units they can control and this will be more than enough to heat and cool 1000 sf or less providing you purchase them to accomadate the correct square footage.The pros and cons of going this route:Pros:Cost.

If you go to their site TREIA has their main meeting tonight and a Rocky Mount meeting on Monday.

As an example I constructed a 4 unit condo building in the Mount Airy neighborhood of Philly at the beginning of the pandemic.
