What is the volume and frequency of contact with brokers?

You could negotiate in a frequency of visits from your property manager that you are satisfied with but you will have to micromanage them to make sure they are actually visiting and then they will probably charge you some ridiculous amount for each one (or a higher percent).If you are burned out on managing your own properties you will have to accept that a PM will not manage them to the same level that you are and be willing to live with the risk that the houses are not being kept up as nice.

Just like with expenses, except you probably list the maintenance item in Column A (clean gutters, change filters, etc), and create however many Columns B-whatever as necessary for the frequency of the item.

The type of collateral, the status of the local real estate market, the strength of the borrower, the terms of the Note (rate, term, payment amount & frequency, balloon, subordination, etc), the payment history of the borrower (seasoning), compliance with origination regulations, with or without recourse.  

The claims frequency for homes under construction is very high.

@Cory DamonIf you will have a frequency of transactions and/or time-sensitivity, then the SDIRA LLC will be the more effective platform from which to operate.You should be able to contribute both to a Solo 401k and a separate Roth IRA.  

-----------------------------------------------------------------You can also call St Pete's Code Enforcement at 727-893-7373 but I imagine they will tell you it is not allowed.The state law you are referring to is SB 356 http://www.flsenate.gov/Session/Bill/2014/0356/Bil...The main point being this:"(b) A local law, ordinance, or regulation may not prohibit vacation rentals, or regulate the duration or frequency of rental of vacation rentals.This paragraph does not apply to any local law, ordinance, or  regulation adopted on or before June 1, 2011."

At the end of the day, it is a judgement call depending on the particular facts and circumstances of the situation.I believe that 2 flip transactions per year would expose an IRA or 401k to UBTI taxation and we would advise our clients intending to flip houses with such frequency to consult with their tax attorney and/or CPA in order to evaluate the potential impact of such taxation on their investment strategy.DisclaimerPlease keep in mind that I am not personally a licensed tax advisor and the following should not be taken as tax advice.At Safeguard Advisors, we have a continual dialog with our tax attorney/CPA on matters of taxation and are well versed in the application of the code to self directed IRA & 401k plans.

Trying to get feel for frequency of environmental studies done on commercial properties and if phase 2 done specifically for underground storage tanks would additional study need to be done on individual structures?

You also have to consider the frequency of occurrence - how often (on average, statistically) is someone going to have an uninsured claim on your property and sue you?
