In DE you have to give 48 hour written notice sent by certificate of mailing. 

Then there os a "De Minimus" deduction amount that you can do for $2,500.

Quote from @Luis De la Puente: In your experience, how do you see private money lenders shaping the real estate market, especially for fix and flip projects?

I live in a cul-de-sac, and had a home share situation next to me for years.  5 guys living in a 4 bedroom house, with 7 vehicles between them. 

I'm located in the Delaware Valley (NJ/PA/DE) area. 

These are typically deductible in the year they’re done.On the other hand, improvements that better the property, restore it after substantial damage, or adapt it for a new use generally have to be capitalized and depreciated over time.Now, if the cost is $2,500 or less, you might be able to use the De Minimis Safe Harbor election to expense it immediately, rather than depreciating it.

I’m a new investor and live in Delaware County.

:)I'll echo what both @Paul De Luca and @Jonathan Klemm have said. 

We have also just purchased land in El Valle de Guadalupe to build in the middle of the corazón of the Valle.

For instance, De Soto, KS, has Panasonic's $4 billion EV battery plant, while the Northland is seeing a $1 billion Google data center, and Meta is developing an $800 million data center between Gladstone and Smithville.
