The return on equity is probably very low considering they are paid off so maybe explore refinancing or selling the lowest performing one(s) or your biggest headaches to reinvest in more lucrative deals.I noticed you also used a metric of number of rentals to attain your goal rather than $$$/month.

I would be surprised if there weren't notices given to both the defaulting End Buyer (You're in default, you must close by X date or we're forfeiting your deposit) as well as the escrow agent (Buyer defaulted, see contract Earnest Money paragraph regarding release) prior to that actually occurring.

I don't know why you would think a tenant requesting notice before you accessed the property would be an "unreasonable demand".

On top of the 2 that are ongoing, I'm permitting for 2 new builds, and I noticed that pool prices came down a few bucks, and my truss prices were 30% less than when I started building 6 months ago.  

Of course I can switch carriers, but the question to you all, is are you noticing insurance carriers getting very picky with certain things, and if so, what?

From google: “The Fair Housing Act (FHA) does not apply to certain types of rentals, including: Owner-occupied buildings: If the building has four or fewer units and is owned by the person who lives there Single-family homes: If the owner rents or sells the home without using a real estate agent, and they own no more than three homes Religious organizations: If the property is only available to members of the organization's religion Private clubs: If the property is only available to members of the club Senior housing: If the property is designated for people who are at least 55 years old Even if a property is exempt from the FHA, it must still comply with the law's ban on discriminatory statements, notices, or advertising.

Notice I say advertised and not going for because next, you will want to see how long these properties have been on the market and if they have decreased their rental asking amount.

And has anyone noticed any particular nuggets to look for?

You have to go through a whole process by sending them a notice to cue etc.
