In my opinion you paid a lot for this rehab and septic tank issue.

Hi,How frequently I have to do septic tank pumping to clean everything. 

I also tell them not to use those dissolving cleaners that you drop in the toilet tank because it can damage parts.My leases also state what appliances are owned by the landlord.Mostly safety stuff I require after that such as no use of candles or space heaters.

Can't tell if this is gas or oil but assuming that they don't have both, should be gas as well.One more note; I do not see an expansion tank in either photo.

@ Chris Tanks thanks for the replyear.  

There are markets within markets, not all markets are doing the same thing at the same time.So what are the zip codes you are talking about that are tanking??

Planning ,   Public works  if its a private water company or public company check in with them to determine sizing.and the fire departments in many areas have minimum fire flow rules for subdivisions  1,500 GPM at the hydrant  Architect would be someone you would hire to actually design your buildings that is farther down the line.. you need to understand what is possible on the property.Or the health department for minimum lot size when served by septic and public water or septic and sewer.. and just bust it up in lots and sell off .. good thing is your fronting public streets already so it could be as easy as taps into the public water and putting in septic tanks and drawing lines for your new lots which a civil engineer would normally do.. you may never need to ever talk to an architect unless your going to actually build something.

She also says lender has a problem with old above ground tanks that leaked oil that was in the appraisal.

Wonderful (from Shark Tank) 70% of the money made from stocks comes from dividends. 

They are not going to fill out a form if they see you as a hungry shark looking to devour their house full of memories.
