Do you really think PA (or other state) law allows to enter to the property without the tenant where also tenants personal belongings without court eviction verdict first?

You'll need this only for a go/no go decision on your 1031.The requirements to defer all tax (a complete exchange) are that you purchase at least as much as your net sale and you use all of the net proceeds to do that.In a partial exchange you are either purchasing less than your net sale or you are taking some cash out of the proceeds. 

And all of the proceeds of all the sales must to into the purchase of the replacement property.

Which would bring you more joy - having the proceeds from a sale or having the property? 

@Brian DavisAs a general rule you would want an LLC in the state where the property is located as it will need situs in that state to be able to act in court,As some state have very low outside liability protection on their LLC it is recommended to have these LLC owned by a holding LLC in a good asset protection state.

Investors are getting more aggressive with their tactics to obtain properties, such as knocking on doors, sending out letters, and using data from court records just to find ways to get properties in the area in such a competitive market.

If the court refuses to process an eviction, file anyway and wait your turn.

In Southern California, the Courts are very pro tenant and can be quite time consuming. 

The trustee would be me.If I place an LP fund which holds an LLC real estate syndication into the trust, and the LLC fund produces income in the form of distributions and capital appreciation/gains, could the 'trust instrument' be used to direct all incoming proceeds to be invested into a bank which then places funds into a 529 plan?

If you properly serve them the notice and they still don't leave then you proceed to filing the eviction.
