If they were separately metered, each tenant would pay the $116.50 base fees and their individual use, which would be 3x higher than what they pay when sharing a meter.There are many options, but don't make it more complicated than it needs to be.

Individuals? 

Oh well.However, if it does come back, what I found was that creating the optional "Individual" FinCEN ID makes things a lot easier. 

I actually keep a list our bookkeeping firm recommends based on firms/individuals we and our Clients have had good experiences with as well as I've personally had good experiences with.

Learn the lawsDon't use a contract "off the internet", laws vary by state and are also regulated on a federal level Learn the financing techniques correctlyDon’t skip parts of the processDon’t ever do a “kitchen table” closingUse the proper deedAn attorney can help you with the legal work, but the rest you are on your ownYour guru will not bail you out“Investing” in someone else’s deal by providing a small 2nd loan so the “investor” can pay for “cash to the seller” and for “closing costs” so he can do the deal is a very bad planKnow what problems can ariseLearn the responses and solutions to problems before they are needed Know everything there is to know about Title and what that meansKnow who a "protected class" individual isLearn the "back doors"Learn human natureUnderstand timelinesUnderstand regulation enforcement (some of these "mistakes" have a 10 year statue of limitations ( they can charge you 10 years AFTER you do the transaction) and carry hefty fines and possible imprisonmentThe court doesn't accept "I didn't know" for an answer"Know that the source of the lead plays a serious role in some states and federallyKnow how much of a "profit" pushes the boundaries to invite an investigationYou can be sued by the seller if you don’t do things correctlyYou are automatically at fault if an investigator or attorney or regulator gets involved.

The IRS defines a “quality” cost segregation study as “a study that is both accurate and well documented with regard to” 1) the classification of property into classes, 2) Explanation of rationale for the classification of the property and 3) substantiation of the cost basis of each asset and reconciliation of the total allocated costs to total actual costs.

(substantial value add opportunity, significant appreciation potential etc.)  

If you are not attached to the duplex, could be a good time to sell to developers who want to convert to individual condo units.

Successful individuals must learn to accept uncertainty, maintain a flexible mindset, and continue to invest.

(Could actually be substantial since we bought another property in 2024 so that sucked up a bunch of time).For 2025, it looks like one of us can take on being a RE prof full time.
