I'm have been asked to enter into a partnership with an experienced investor, and I'm not sure how to or the best way to structure a partnership.

Hi Lamier and welcome to the BiggerPocket's Community!

@Steve Babiak, unless he registered with Pennsylvania as a contractor, he would not show up on there, the company as the OP stated is from NJ where he would be registered. he should be registered in PA if he is doing work there, so i agree, he should have shown up on those sites, i am a contractor in NJ but do not do work in PA, not even my own properties, so i do not show up on those sites.

At some point, the juice isn't worth the squeeze for us and we just want to enjoy life. 

Just make sure the other two assets can still cash flow with the debt you put on them.I have an 10 unit commercial property that is basically cash flow neutral because of large Capex expenses that come up every year.

What tips do you have for someone just getting started?

Many people know about the Hidden Rivers underneath some of the foundations in New York.

There are no problems being a landlord , just buy a property take the first renter that applies and rake in the cash . 

For example:Second, under their "About us" link, click on "Management" and you'll see a "Meet the Team" page where there's the following photo/info for this James LaPushner fellow you mentioned (which says he was born in New Zealand):However, if you do a reverse Google image search on this photo, you'll find that it's posted on several other sites, including this one: https://planetaseminarov.ru/people/konstantin-baksht.htmlHere's a photo of him from this page:This page is written in Russian, but if you translate it, it says his name is Konstantin Baksht, he lives in Moscow Russia, and he is the owner and CEO of the international consulting company Baksht Consulting Group. 

At the numbers you are talking about and where the market is heading you could pick up some very high quality NNN national credit tenant properties as commercial continues to recover.
