Usually, on a constructed property, you never have to worry about this unless you doing some sort of signficant modification, such as adding on an addition or maybe putting up a fence (e.g. how far does the fence have to be off the property line, how high can it be, etc.). 

For all the reasons you mentioned and I'm planning on a few modifications at some point.

Owner occupied needs to get offer accepted by July 15 to be in the house for the school year, that piece of purchase market will slow way down come August 10. 4 million people in forbearance, with no modification happening yet.

Are there any modifications to the written lease?

So I was in a crunch now that my buyers were living in the house and waiting to close.so I ended up having to do a loan modification with my hard money lender dropped it down to 12% over 30yrs.

The bank offered me a modification to my loan, which would extend my mortgage from 28 years to 40 but reduce my monthly payment from $1325 to $1110 (interest rate from 3.99% to 2.875%). 

Are there any modifications to the written lease?

By hml you are talking about home modification loan?

After the modification, the house would be close to 1800 sqft. 

In my 9 to 5, I'm an account manager and project developer focused on service and turnkey projects related to HVAC and energy management with some experience in lighting, plumbing, and structural modification.
