You may also want to call local property management companies to get their estimated rental amount and their feel for the rental appeal of your property in the area, etc.* Talk to your tax professional and find out what your tax implications are from inheriting the property to buying out your brother and putting it in an LLC, etc. * Also find out if the property's tax assessment changes with any of the scenarios above.

The process usually goes like this:Rental Listing -> Landlord and Prospective Tenant fill out and submit RTA -> Voucher office performs Affordability Study -> Landlord approves estimated rent amount -> Property Inspection -> Approval of Property by Voucher Office -> Lease & Move-InThe section 8 process in/around Baltimore and Baltimore County does take a long time these days.

There are 2 ways to look at an investment to make sure you are safe: Long-term hold analysis, and Fix & Flip analysis. 

Each of those markets will require different amounts of capital to get deals done. 

As for the revenue, I would rely on a property manager to verify/weigh in on the rent amounts. 

If you tell them you're a landlord and you own the property but aren't living in it, they should be able to quote you for liability, the house, and a much smaller amount of personal property (appliances like your fridge or stove)

I intended to BRRRR the property & spent about $40k total to fix it up.

I’ve been eyeing a few off-market deals that would allow me to pull out a good amount of equity after rehab, but then the monthly mortgage payment is the same as market rent.

It's the same amount of depreciation no matter how fast you receive it, but getting it in larger chunks sooner means more cash in your pocket now for more investing.

My goal is to purchase one or two homes this year to fix and flip.
