We really mostly need tools to render data well and something that has nice canned reporting features for tracking procurement of leads, CAC, etc.  

. - Install two new high efficiency condensing boilers, and update windows and insulation for better heat loss performance.PROS - a) minimally invasive; b) can provide 15-30% reduction in heating costs (we are told).CONS - a)total gas expense is still paid by the landlord; b) individual units won't have individual control (except for a thermostat controlled shutoff valve for heat/water in each unit); c) AC would be available on with in wall/window units. 2) Try to individually meter each units' gas and provide each with a traditional forced air heating/cooling system.PROS: a)gas expense could be completely removed for landlord (huge)- even tankless hot water could be installed in each unit; b) each unit would have their own climate control.CONS: a) constructions costs of running new gas lines and soffiting sheet metal duct work. b) highly invasive with collateral construction costs; c) future costs of maintenance on multiple systems vs a single building-wide system. 3) An electric based heating system- This is tricky in my mind because of the high cost of electric heat.

IMO conversion to CAC, especially in a home that size, is a no brainer.  

CAC with $170k down is 10.5% (at $650k purchase price)I see you're in Liverpool.

Not a deal breaker in Baltimore, but be sure to only look at houses without CAC when doing rental or ARV comps.

I recently went under contract for a 4-unit multifamily property in Fresno, CA (C-Class neighborhood, 93726 AC for those familiar) for 385k with the intention of house hacking. 

HUD, CAC, nobody.

I add CAC and make them lead free.

Also what is a good monthly CAC return and appreciation anticipated?

My #1 advice to people that are still in contemplating getting out is to make sure that all of your injuries are documented because the Army- military will surprisingly take care of you on the other end with disability.I didn’t even know what disability was- I thought the only perk of the military after you’re out was the GI bill, but I ended up getting medically discharged because my back and a few other things and I now have a retirement card that will allow me on any military installation just like your cac card.
