I believe they should do a 1031 exchange into a truly passive investment with monthly income.

You may not need to do a 1031 exchange.

As recently as Mar 23 I have a text exchange that goes something like this:Me after receiving update on her moving progress:  Ok will consider April as the last month as discussedTo which she responds: ok (then some more updates on moving)Then she's gone end of March, less than 30 days even, and I'm left with an empty unit for April.So if the new month comes before the 30 day period is up, does she legally owe all of April rent or only as much of April until that 30 day mark it hit?

Just looking to grow my network and exchange ideas / experiences. 

I have found a few run-down vacant homes; the owners owe a few years in taxes. could i offer to pay the taxes for them in exchange of the house?

A syndication group that we worked with on another deal (much simpler deal) has proposed to invest roughly $300,000 into the deal for the entitlement fees (and them handling all of the leg work) in exchange for a percentage of my grant deed.

Learn one thing, then move on to the next item.Because there are some things you don't have to learn, you only need money to pay someone who already knows it such as an attorney, or a CPA or a 1031 exchange specialist, etc...Good Luck!

When the income the plan receives is not taxed, but rather available to be reinvested, you gain the benefits of compounding that tax savings over time, and will be able to mushroom the savings value considerably as a result.In exchange for that tax-sheltered status of the IRA, there are rules to keep everything isolated within the IRA. 

you only have to for 6 months, but if you have a family or friend that could allow you then just pay for their utilities in exchange

First of all, the don’t actually do anything preventative such as lubing or cleaning.Back in the day, HVAC tune ups actually consisted of coil cleaning and perhaps electric relay exchanges , etc.
