I thought the buyer was to take on the remaining balance of the mortgage. 

Any advice on what I can do with the remaining part of my time?

For some reason there are 3 APNs for 1600 Pennsylvania Ave, that's just one of the three.Your agent or loan officer shouldn't have any issue with taking 5 seconds to pull that up and email it to you, provided you're not asking for 50 a week.The one I use (which is just the one from the title company with the cleanest UI) says "Property profile: 470 of 500 remaining," implying that there is/should be some monthly charge or limit, but every time it drops below 450 it resets for 500.

I have someone who has a remaining mortgage of 110k and comps are 230 range. 15k in repairs.

Next cleaning I plan on pretreating the high traffic areas to remove the remaining dirt.

So upon closing, the building may remain empty for 1-2 months while I do the repairs and put in a laundry, so these numbers are projected based on my knowledge of the rents in the area:Annual Rent Two 2 Bedroom Apts                   $ 18,600  Annual Rent for 4 Rooms                                    26,260Projected Laundry Revenues                                4,200Total Rents                                                        $ 49,060Expenses: Taxes                                                               4,088Water and Sewer                                              1,600Insurance                                                          1,600Vacancy & Credit Loss (6%)                             2,944Repair Reserve (10%)                                       4,906 Electric                                                               1,800Trash                                                                      840           Total Expense                                                      17,778            Net income                                                          31,282             Purchase Price                                                   134,250          Cap Rate                                                               23.30%          Cash on Cash Return After Mortgage                   91.17%I'm always cautious in thinking something is a slam dunk and there will be some challenges managing the rooms, but there are only 4 of them. 

If it is your first property you can buy another home with the remaining balance and rent out the first property, which is what I'm trying to do.

I mailed 500 out this week and have the remaining 498 going out in two weeks. 

I'd love for someone to prove to me that converting to a triplex in an R2 hood is only a minor variance, though.If you don't mind moving and renting out both units of your duplex, then 10k can get you another duplex easily with 5% down.I think that if you put 10k in renos and tried to refi youd get no money out after all of the fees and filling in the remaining gap to 20%.
