The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

If I'm an out of state investor, is this income tax based upon income made in Ohio or does it include all my income, regardless of where I've earned it?  

If you have an LLC, ownership percentages are recorded and thus difficult and/or costly to change if an active partner is earning equity through actions.To give some personal experience, Lending and banking can be difficult at best, impossible at worst with a Land Trust.  

Also, have you made any significant alterations to the property or if it were put on the market today, would it be indistinguishable from a standard 4-bedoom house (are there any extra walls for the SRO, constructed locks/barriers etc.)If its a standard SFR and the leases are very short term - there is a path that you could refinance this with a DSCR as basically a Short Term Rental and then potentially change strategic course back to SRO if needed at a later date

I can easily grade, gravel, and fence off the rear 2 acres for outside storage that would easily bring in an extra 4k a month.

I’ve been interested in getting into real estate as a way to potentially have extra income and also have more of a safety net in retirement, either through cashing in on equity or continuing to own rentals.

How long does it usually take to earn your first commission?

If you aren’t earning as much from STR then MTR might be the way to go. 

Something draining cash that I propose to take over and pay the owner some extra cash, that I can’t understand.  

If you have pre-tax and post tax Roth funds in the existing 401k, you will initiate a rollover into a newly formed Solo 401(k), with some funds dropping into the pre-tax bucket and Roth funds dropping into Roth bucket. 3) 3 benefits that I find many real estate investors are attracted to with the Solo 401(k): 1) Higher Contribution Limits (providing you have enough earned income) 2) Ability to contribute to Roth, without MAGI limits where you have to do a backdoor contribution, like you do a Roth IRA. 3) Exemption from UBIT/UDFI on debt financed real estate deals, this could be directly, or through a syndication type deal. 4) Now, we can proceed with, what about the caveats and qualifications to open and maintain a Solo 401(k): 1) You need to have earned income from the business/sole prop. that is sponsoring the Solo 401(k).
