That will expose you as a SFR investor.

On a side note, if you are going for cash flow, I personally would not expose myself to that much risk for only $900/mo across 37 units. 

Also have your financing or cash ready so when a good deal exposes itself you can strike quickly.

Would it make sense to split the electric and put two meters, since the lower unit walls have to be exposed anyway.

You have to remove/peel back the trim to expose the glass.

--Are you then exposed to UBIT since it's in a SDIRA? 

That would be a great way of getting exposed to properties and some common issues that landlords/owners deal with.

You cannot buy a property and leave it vacant most of the year without it being a drain on your income and exposing yourself to some serious dangers.You cannot just leave the property vacant and not expect bad things to happen. 

@Brandon KompYou may be exposed to depreciation recapture and capital gains tax upon the sale of an investment property.Capital gains tax rates are 0%, 15% or 20% depending on your overall tax bracket.You may also be hit with an additional 3.8% net investment income tax depending on your bracket.Depreciation recapture is taxed at a maximum tax rate of 25%.If your marginal tax rate is 37% - the depreciation recapture will be taxed at 25%if your marginal tax rate is 12% - the depreciation recapture will be taxed at 12%

I expose every bad thing I can think of - especially when it comes to location.
