I'm getting good at sniffing them out thanks to these common red flags: they often have a foreign accent, they can't meet in person, they are looking for a quick cash sale so they're okay with me listing it below comps, don't want a "For Sale" sign placed at the property, etc. 

Checking most recent tax year for tax prorations, instead of most recent mill levy (big difference since taxes went up 30-35% last year, $10k screw up I saw in real life by a buyer last year)3.

Your greatest challenge is going to be running this management company without the appearance of co-mingling all of the LLCs together.Bear in mind that one of the things that you'll be doing here is converting Passive Income to Earned Income via the Mgmt Company and that will be subject to self employment tax whereas had you left everything in the property LLCs, you'd have only passive income. 

Basically trying to get the most tax benefits and protection as possible.

My tax lady said it’ll be considered a loss and not to worry about it.

For example the last rental property we purchased we owe on it about $86K and if paid off would cashflow an additional $600 per month.Because of our household income I am worried that paying off properties would bring us into tax brackets. 

From what i have heard, taxes 2% of the sales price, insurance varies between $3-5k, and HOA also varies.

Some are saying that by adding me to the trust, we will have to pay the transfer tax (for my portion only) because I am not on title.

Insurance has gone up quite a bit, property taxes and HOA fees as well.

@Kevin Drouillard most PMCs do not pursue collections after a tenant moves out.Check the eviction judgment to see if a money judgment was included.If not, you will need to pursue small claims judgment.Once you have a money judgment you can try to garnish (another court process) wages, bank accounts or state tax refunds.
