I would advise strongly against doing new construction on your first venture unless you are partnering with a builder.New construction has elements of an advanced nature such as; accurate bidding, navigating the local municipality zoning and permitting, having the knowledge to work through soil suitability, detailed architectural elements and so forth.  

Here are some links showing the development plans along the riverfront as well as a new luxury apartment complex.https://www.timesherald.com/news/new-lease-on-life-for-condemned-sandy-street-building-in-norristown/article_d2f0efcd-6528-5a59-8ab6-20ad28153b03.htmlhttps://www.norristown.org/424...https://www.norristown.org/Doc...Hope this helps shed some light on the area.

They are basic gravity fed systems - helps that we have really Sandy soils.

On larger sites I've even turned the soil to get some good sand below 10' and stack it in piles...then backfill it with top soil and extra clay (of course in areas not being utilized for traffic.  

Hi Sandy,BK is one of the "must check" items before you buy and while you own a note.

@Sandy Uhlmann you would need to consult an attorney about that but keep in mind an MLO only costs about $350 and it's well worth it to have a solid note deal that will hold up in court or enable you to sell the note later if you wanted to.  

@Sam Sand I grew up near Wilmington, went to school there, and my mother currently works there...there are parts that I've noticed that look completely different from when I was a kid in the 90s to now.I'm not currently investing there now, but maybe in the future I will.I'm currently working on my 1st project in Chester,Pa

Also, your lot size, access, topography, soil make-up, utility tie ins/upgrades, etc can cost as much as the actual construction.If you are looking for a really basic cost per door: I have a builder tell me (without plans) that he believes he could build a 20 unit complex for about 150-175k/door on an easy access wide open lot.
