Getting 25% down and 4.0% rate seems optimistic for the tenant base you are describing.That's more for Aspen Dental, T-mobile, Starbucks with brand new 10 year leases and strong guarantor companies.

If a toilet is clogged because the tenants child threw a shoe down there (or an older female child flushed a feminine hygiene product that clogged the system) the tenant becomes responsible for this repair. 

There's no retirement matching fund, no dental, vision, or other types of "plans", so be ready to pay for all of that out of pocket. 

Either way, special purpose building, they’re not going to rent out tomorrow to a law office or dental practice… Get a contact who will pull title for you, check the last date and the amount of the most recent financial transaction there was on the property.

I am hoping to find other dentists in the area who also invests in RE in order to discuss strategies, goals, and how to balance RE investing with a dental career. 

You or your accountant will decide if you should file using the standard deduction or itemized deduction.Typically you or your accountant will decide what deduction option will save you more in taxes.The standard deduction are the following:$12,550 for single filers$12,550 for married couples filing separately$18,800 for heads of households$25,100 for married couples filing jointlyCost that can be used for itemized deductions:Real estate taxesPersonal property taxesMortgage interestStudent loan interestGifts to charityPossibly medical and dental expensesThe mortgage interest deduction is a tax incentive for homeowners.

These does not affect the quality of life (safety, hygiene, security) and are mainly aesthetics.

Sure, but factor in that I take them to and from school every day, can't even claim them as dependents on my taxes, provide full medical, dental and vision coverage.. and they stay at my house overnight 50% of the time, and I'm probably paying too much.

In the thought of if I could have my living experience be whatever I wanted...what would it look like.I came up with this list: Barber shop / Salon pallor, Car wash center, neighborhood grocery story (with good produce, beer/wine, premade but fresh over ready meals, and all my hygiene needs, on site bar or restaurant, community gathering area, a co-working space with small offices I could rent if need but a shared space also, a lap swimming pool, a real deal gym (not a hotel gym), sauna, on site laundry service (offered at a premium), and on site cleaning crew (additional cost of course) to clean my place.All of these things would be set up as additional sources of revenue for the apartment some that are directly operated others that just lease out space (like the salon parlor or something)Structurally it could look something like this: Sub basement: Lap pool / locker rooms / saunaBasement: Full real deal gym (anytime fitness level type) - could be directly operated or space leasedFirst floor: The amenities floor - could be directly operated or space leased2nd or third floor: Shared co-working space (residents get a discount and are priortized but its still open to the public for a cost)All floors above are living space.Has anyone ever though of this before?

., hygiene products, paint, grease and oil, hair, dental floss – all of these can cause clogs and prevent drainage).I'll be living there myself first for only a year and will rent it out afterward.
