We are constrained on the West, South and North and East quickly becomes harsh. 

Replace all TCs, drain water, add chemicals in all toilets to kill roots in the system.

I look forward to seeing yall's responses.Thanks,Harsh Singh

Heat and chemical.

The pest company should take on treatment for termites, framing work, and anything that requires chemical treatment. 

If not you will need to pay a premium to get a 3-4 plex even if work is needed there will be no value play.A little harsh I realize, but the scarcity of 3-4plex is real and you need to know what you're dealing with so if you find the right one you are ready to lock it up rather than screw around and lose it.

@Harsh Patel , @Jay Hinrichs nailed it, as usual - if a provider uses 'used car salesman' tactics and 'scarcity' language, it's time to run!

I think, from what I've gathered via this discussion, is that our contingency was too harsh and due diligence too long and that we should offer more in earnest money. 

Please make sure you or workers wear cartridge style air respirator when removing that carpet and spraying with any of these strong chemicals also probably should wear a white tyvek style suit etc. 

Septic companies around here dont clean drainfield lines , they just replace ( around $ 20K with the new systems ) So I am figuring on about 200 bucks in stone and 80 dollars in fittings and 100 in chemicals .
