Blogging is a commitment and a real skill to find the right blend of material and the right frequency for your audience.While I'm now highly skilled at blogging, I'm not sure that I could maintain a successful RE Blog that people would want to read or follow as there is so much excellent subject matter content out there (and here) already and I'd have little value to add.It pretty much comes down to the goal of what you're trying to accomplish.

You want to spell out the amount, the interest rate, when it's computed, the payment frequency, any minimum or maximum payment amount, late fees, etc.The difference between 8 and 9% is 12.5% of the return your lender is getting.

Flipping houses, if conducted with any regularity or frequency (more than a few a year) will subject the IRA to Unrelated Business Income Tax (UBIT), which can be as high as 39.6%.  

Marijuana does not do damage like nicotine from cigarettesIt's all about frequency of use.  

Google youtube and septic tank pumping frequency.

I recommend frequency on prospecting for sites to publish your content and look for relevant places to post.Over time the compounding of content on your site and your link development efforts will drive up your leads which come from your site for free (or your cost to build content/links) as well as your AdWords costs will go down due to Google's QualityScore.

I lifted this out of a BP post.The need for them to secure renter's insurance.In the event of a tropical storm or hurricane watch or hurricane warning, who is responsible to install storm shutters and how far ahead of time etc...Operation and frequency of the sprinkler system - only for SFR properties.

I don't see a need for much past the loan amount, interest rate, payment amount & frequency.

Some custodians have stopped accepting single member LLCs as IRA investments all together.The frequency of profit distributions should be spelled out in the LLC's operating agreement, I would consult with an attorney relative to any requirements that may be in place.It should also be noted that there are special provisions in place when a multi-member LLC with IRA investors attempts to secure financing for purchases.

Cost recovery issues (frequency of cleaning, repairs & maintenance, etc), insurance, etc.
