@Mark De sagun welcome to BiggerPockets it sounds like you have a good plan in place.  

The furnace was about $2300.Can I expense the furnace under the de minimus safe harbor election (because it was less than $2500), and then capitalize the air conditioner (because it was more than $2500)?

@Aldrich De Jongh, assuming you can get it for the 15% off the asking price, your repair costs are accurate and bring rents to the high end of the area, it looks pretty decent from my perspective as well! 

As an out-of-state investor (Live in PA and have property in DE), we do our own property management (Short-term Vacation Rental Condo) - HOA does all the outside and pool stuff and we book, stock, and clean it ourselves...so I can't help you there either.   

@Shannon Phillips have you ever considered a Delaware Statutory Trust (DST)?

Right now im looking to connect with anyone who is in New Jersey, Pennsylvania, New York, Delaware, and Virgina.

I'm an out-of-state investor who lives in Seattle, though originally grew up in Delaware, and want to start investing in an area near home for me.

Ideally in Chester or Delaware county.
