I do own two triplexes in Scranton, and I will say the one issue is that you are going to be taking care of the utilities normally if they are not on separate meters, which could take a good amount of money away from your overall cash flow. 

There are two reasons this is a bad idea.Investing with an SDIRA (assuming it is not a Roth) will often result in paying significantly more taxes. 

Two best options are house hack or sell and acquire a 1031 property.

Last two years I averaged $4300 for the season.

Both assets have two ways to make you money:Regular income (rent/dividends)Appreciation (property value/stock price)🛠️ Control FactorNow, here's where real estate often shines - you have more control!

I own two rentals in Indiana.

I’ve found better results using my acquisition framework in the 10-50 unit space where there is one, maybe two owners.  

However, if you sell instead of rebuilding, the IRS may include part of the payout in your taxable gain unless reinvested under the §1033 involuntary conversion rules, which allow you to defer taxes by purchasing a similar property within two years.If the property was your primary residence, you may exclude up to $250K (single) or $500K (married) of gains if you lived there for at least 2 of the last 5 years, likely resulting in no taxes owed.

If you are taking out a conventional mortgage of any kind, you can't buy in the LLC as it does not have two years of tax returns.You are also asking if an entire state is good to buy multifamily, which means you are too soon in the process to even talk about buying.
