This surely affects my CoC ROI and the amount of money I would need upfront.I didn't process the preapproval request yet as I was wondering if that was all fairly standard? 

We have all of this information internally from our property management division.It took a lot of time to develop though

Maybe go chat wit the title company and see what is standard for your area.  

To the best of my knowledge, most Arizona lenders use the EPA drinking water standards requiring a maximum of 0.010 mg/L (10 PPB) arsenic. 

If you delead, and maintain the standard, you will be in the clear.Here's the law (emphasis added by me):460.100: Duty of Owner(s) of Residential Premises (B) Whenever any residential premises containing dangerous levels of lead in paint, plaster or other accessible structural material undergoes a change of ownership and as a result a child younger than six years old will become or will continue to be a resident therein, the new owner shall have 90 days after becoming the owner to obtain a Letter of Full Compliance or a Letter of Interim Control, except that if a child younger than six years old who is lead poisoned resides therein, the owner shall not be eligible for interim control, unless the Director grants a waiver pursuant to 105 CMR 460.100(A)(3).

@Ben Stoodley The only max rehab cost for the Standard 203k is the FHA max loan limit. 

Once you get face to face with them, you can use it to your advantage and let them know about the standards you need to maintain when dealing with sellers.

Setting the appraised price to the purchase price isn’t standard across the US.

@Basilio Alcantara Hi Basilio, the Florida Bar Association has a standard, approved lease that is very thorough and comprehensive.

Most lenders, although not all, intend to resell your loan after they close on it, which means it needs to meet strict criterias that are pretty standard across most of them.Now, your options could be to:* Go to a non-conventional lender, but be prepared to deal with much higher rates and closing costs.* Explore the commercial properties route - where they look more at your downpayment + ability of the property to service the debt, rather than your W2.* Do the house under your wife's name (if she still has a W2)The first 2 options will either mean high rates or high amount of funds down.
