Labor/material are going to be different and need to factor that in4) new roof, new HVAC, new water heater, ac panel, replacing plumbing to PVCThese are very variable, if you are getting this from a licensed guy to do it and unlicensed.. is it a big shop or a local shop doing it, is the GC doing it they will put some money on the top so it will be more money5) framing (creating new bedrooms or baths)I would get all these quoted from a good couple of licensed guys and unlicensed to know your numbers to cents

The insurances like AAA are strict on the paint, roof, plumbing, electric etcThe houses are in Stockton, California.Thanks

@Olga K.It doesn’t necessarily confirm the sewer line is completely blocked—it might just be an issue with the internal plumbing or fixtures.

Another guy wouldn't pass me at all because I showed him up...yet another kept insisting that his interpretation of a plumbing code was correct when it was not - cost me 1 month of time.A neccessary evil IMO, they were usually former GCs who couldn't make it in the real world.....  

If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

@Diana Teng there are a LOT of potential pitfalls:(So, it's vitaly important to not just find someone that you think you can trust because they tell you what you want to hear, but you find someone that their processes seem a good fit for what you want.EXAMPLE: we do BRRR Turnkeys for clients and take numerous vides we share with them - initial, worst state of any demo, when HVAC, plumbing, electrical update BEFORE walled in, before any major payouts and of course a final walk-thru video.One thing that's accurate from all the HGTV renovation/flip shows is that you should expect and plan for surprises!

Quote from @Arun Maheshwari: Hi,Does the bank owned foreclosure property allows to put Inspection contingency for big issues like plumbing, eletricity etc.ThanksIf it is bank owned and the foreclosure has taken place - possibly but they would make you responsible to turn on power and water and turn it back off.

It's understandable that unexpected things arise sometimes, especially when you're opening up walls or dealing with older electric or plumbing.

Check w/ the City / County to see what the permitting process is, and what if anything you would have to do regarding plumbing / electrical.

We have a clause in our lease that plumbing clogs not caused by mechanical/material defects in the plumbing will be charged to the tenant, and if your lease doesn't have similar I would recommend such a clause.
