The AGE of the house is seldom an issue unless you're working on a Victorian cottage.Major issues in any market:current inventory;  few or many of similar comps (same configuration+sqft, not age) DOM for recent comps soldaverage listing price for comps soldyour curb appeal vs compsSome markets are naturally slow so bridle your expectation.You are correctly concerned regarding getting the listing price right. 

The configuration with the concrete posts would make it difficult to get a car in there, much less 2 or 3.

A lot of corporate customers have specific configurations, and requirements.

I don't need someone who is going to do all the things I've already done and then want commission when 6 months down the road we get lucky via someone seeing a sign on the property.It's currently configured as a DRs office, 1500 sf.

Will net about $750more/mo than the preexisting configuration even after the increases utilities bill on my part.

However, I think larger SFH houses could be configured this way.  

@Matt BYes, for you to sell, transfer or gift the existing LLC from yourself to the IRA would be self-dealing and create a prohibited transaction.The IRA owned LLC is specialized in nature and needs to be configured to meet the compliance requirements of your IRA custodian.  

If they are on a single parcel and depending on the configuration, a lot line adjustment may be a value add opportunity provided there is a large enough spread between residential and commercial properties.

@Teri S.Trying to engage in an investment activity that requires frequent transactions or transactions that are time sensitive in nature is not easy with a 3rd party custodian acting as the processor.A self-directed IRA LLC or Solo 401(k) can be configured to offer checkbook control.  

I'm vested in MFU's and I'll give you my take.SFR & MFU appreciate differentlyexpenses are comparable but the MFU has more doors hence more GSI & NOIOn (1), the SFR 'competes' via comps with others in the community of like configurations (2/1, 3/1, 3/2) and is dependent upon the community economy.
