Our prop taxes do not go up proportional to rental income, the way it does in 49 states.

@Rick Gonzalez, If you're talking about extensions on the 45 and 180 day time frames then your only bet is to pray for an earthquake or hurricane of such proportion that the IRS gives a disaster extension for all filings in the affected area and that you are in that affected area. 

I'm trying to avoid hard money loans; I've heard rumors of bank programs where they will loan a proportion of ARV as a construction loan that becomes a mortgage after it is done.

I'm not capped at 10 houses by my bank, but I agree that using hard money at 10%+ isn't something appealing to me.Regarding raising capital, I've never seen much of an advantage in getting together a number of partners/investors and sharing proportionally in the return. 

Hence, when you sell, you can divvy up profits in proportion to your LLC ownership interest.

Additionally any repairs that need to be made will have to be paid out of your self-directed IRA in proportion with the percentage split of the property that your self-directed IRA owns, so make sure you have a reserve amount available (if you pay for any repairs "out of pocket" this can jeopardize the status of your IRA.)

I've often found the value of mentorship was inversely proportional to the cost, the more you pay, the less you get - though not always 100% true.Knowledge is the most important factor in real estate, beyond money and credit. 

They're will also need to be an adjustment made in their current estate plan to compensate your sibling in some way and at some point for a proportional offset of your share of the inheritance to her, which will be determined now.  

Personally, I'm more of a 'hands on' type of investor and I think the real value you build with real estate is directly proportional to the amount of work (or money) you're willing to put in.

But that is just me and I am a tad bias.Also, proportions are just that....
