When your construction guy walked the property did you go in every unit and inspect all of the mechanical systems?

If so I go on to the mechanicals since they are the big ticket items - electrical, plumbing, heating/cooling.

I'm not certain of the mechanics of the auditor's office now that there has been a change in structure, but generally we make assumptions of taxes based on the purchase price or the current tax assessment, whichever is higher.

There is no one size fits all here...but I will say that anyone doing Wholesaling (licensed or not) should consult with their Real Estate Attorney as to the required language in the contract and overall mechanics of the transaction (what actions create an Equitable Interest) so that if someone does challenge it, that same Attorney can defend his guidance (so long as you actually followed their guidance of course..lol) in court or a Commission Hearing

Looks like $7500 for mechanicals (plumbing and HVAC)), $15000 on the remainder of the project for inside.  

First off, knowing your numbers and your market is key to your success, but aside from that, if you make an offer with no contingency days, by the time the seller accepts your offer and your EMD is due into escrow, you have at least 2-3 days to perform any necessary inspections like termite, roof, mechanicals, etc.

Hi i'm Bobbie, 28 y/o plumbing and heating mechanic.  

Has anyone ever built a mechanism like this into their business model?

I'd start thinking about using a GC if there are structural problems, wood rot, mechanical work, either plumbing or electrical, roof work, or more complicated carpentry such as hanging doors, repairing stairs and so on.

Currently I work full time for Boeing on the 787 as a mechanic.
