Nice job! 

Quote from @Kavya Veerapaneni: Hi BiggerPockets Community,I’m relocating to Danbury, CT, from Reading, PA, after accepting a new job.

In IL sellers are not required to share the report, but they're not barred from it either. 

It's easy to obtain, costs very little, and doesn't require extra, on-going effort to maintain.

Understand Their Process – Clarify loan requirements, turnaround time, and potential challenges before moving forward.

As others have noted, it's not perfect (no software solution will be), but It does get the job done.

So it does appear to be possible to get an FHA 203k loan for a 5-unit & convert to a 4-unit.When possible, aim for the Limited (aka Streamline) 203k loan, as it's less complex, not required to get an FHA consultant, etc.Of course, this is based of the two following important assumptions:1)  zoning allows for this2)  and obviously I owner occupy for at least 12 months3)  the total purchase price + renovations are within the FHA loan limits specific to my areaWhat I'm confused about is the timeline or chronological order of the process? 

It's a very expensive repair (ballpark $15,000) and the cost depends on how long the sewer line is.A lot of municipalities here require dye tests and occupancy inspections.

In addition, the Grantor will probably be required to sign the same seller's affidavit that are needed for a non DIL closing. 

I suspect I can build this in 6 to 10 hours, but it is always helpful to have another brain on the job. 3) There is an advanced function I would like to build, but sadly I can't recall the mathematical functions necessary to make the calculations.
