Self managing should be easy, if not then that Realtor can probably help you with the rental side of it. 

Sometimes they forget to tell you that many tenants in Detroit don't pay (depending on the property manager skill and the type of tenant) - but taxes are very high in the city and so is insurance. 

Consult a CPA to ensure compliance with tax regulations and explore strategies that align with your goals, such as providing for your mom while managing tax implications effectively.This post does not create a CPA-Client relationship.

I have two options 6.625% 30 year or 6.15% 15 yearI want to invest aggressively in the near future on more propertiesThe loan is only $110k and the monthly payment for 15 year is $563 and $750I will earn 2-3k a month in gross rental revenueThe property is in a declining population areaRecently rennovated, and all major things were relatively recently improved such as plumbing, the roof, a/c, electric, etc.Will require a lot of management as it is rent by the room so I may switch to a normal rental after 10 yearsI'm trying to find what will mathematically net me the most money in the long run.

I used it to list my properties, screen tenants, manage payments, send notifications, manage maintenance.

I have a long rennovation project I bought in the summer that I am currently working on and am looking to get a few turnkeys on top of that.

Managing 17 shopping centers and selecting sites for new developments is no small feat—kudos to you!

The only other options I can see are A) your mom partnering with you rather then selling the property to you - you become 50% owner and bring the funds and management to the rental while she provides the existing equity as her contribution; or B) your mom lending you the rehab cash out of her personal funds while also seller financing the house to you. 

We manage 4 Bloomington STRs, one being on Lake Monroe.

The property was rented and generated $160 cash flow after mortgage, taxes, insurance and property management fees were paid.
