Its extremely important when running tighter margins like what you're talking about to focus on age of HVAC, water heater, appliances, roof, etc.

For all the deals here in South Florida, I'm not able to do 70%, and it seems like the profit margin is really small.

I don't say it is or isn't worth it - only each of us can make that decision - but I criticize no one for asking the question regarding enough, or even recognizing their lack of desire to spend an inordinate amount of effort to obtain what they consider marginal gains. 

Margins are already tight enough let alone taking on a triplex gas bill.  

We discovered margins are high here and not all that sensitive to construction or sales price adjustments.The design process is getting along well, but there is still much to be done.

The equity market skyrocketed in margin for Nov24 by almost 10% MoM and 29% YoY. 

Usually I lean toward buy and hold but that would be a great profit margin on a flip.
