Also, even if they have purchased a home before, they aren’t necessarily that savvy so it may take days to week or more for them to get all the paperwork together for a loan officer to figure out what they can lend (ie people have lives and also not always “clean W2” salaries).While I work with plenty of clients who don’t have their financing set when I meet them (or day they do but can’t prove it), required PoF is important to make sure you aren’t wasting the Realtor’s time, or fall in love with a house you can’t afford.Case in point.

You could also leave some cleaning supplies around for mailboxes and railings.

Could it not be cleaned up?

My second purchase was another SF circa 1987 - the inspection report wasn't as clean, but I had foundation/structural experts come through to be safe. 

I'd like to start the clean up and get that house on the market.

@Sami Gren call a new lender and see if they can match or beat your current rate, they might as interest rates have dropped recently, don't give yourself an artificial deadline to "keep your rate"  It takes as long as it takes to get the results and if they come back with contamination it can be very expensive to clean up.

@Rohan Deshpande here in California retail buyers will want a certification by a Septic company that both tanks are ok (preferably recently pumped) and a leach field test.Local Septic companies may have records on pumping dates, service done, vault head and clean out locations."

Bushes so close tot he house is bad for the foundation.Also sellers want a clean elevation.

Be clean and respectful of the place you are working at.

I purchased some land, got lots cleaned off and permits, then a week later before I got funding  covid19 hit.
