To echo the rest of the group, if you're planning on holding the property, a DSCR is likely your best bet, assuming your investment property is in a rental area that supports the debt service. 

I said no but it maybe cost you 50 bucks a month other wise your tenant is paying off your principal and 3 to 5 years goes aweful quick then you own it free and clear and you just put 10% down and tenant paid of the rest what are you really going to do with 100 a month anyway... it was funny that was a hard sell. but I can tell you I did about 50 of the no interest and as they paid off you talk about a happy buyer getting their reconveyance deed in such a short amount of time.. 

The mortgage company gets paid off first, then in a traditional sale, the rest minus agent fees and utilities and closing costs goes to the seller.

Kit showers or tiling, or tiling the shower (hot mop or tub shower then tile the rest) all are different3) what is the cost to renew the floor with a LVP?

Given the abatement option could you continue to occupy 15% of the building with commercial tenants while the rest of the building is converted or is that a logistical nightmare/ideally are you seeking different long term commercial tenants if you go that route? 

Having said that, there are some pockets near the RTA off Superior and those that border Cleveland Heights can be ok but the rest of it, stay away. 

Whatever I do, I would need to do with a HELOC—effectively financing 100% of the property (down payment and closing financed with HELOC, rest of purchase financed with a mortgage). 

More likely that the document is correct, and the change to 12% was made recently. 12% seems to be middle of the road but still pretty decent, yet generally Baltimore city RE is a bit more risky than rest of MD .Lonnie Pickard

The property would be a multi family that me and my wife would live in one unit and rent out the rest.

And, I think you can rest assured that somewhere among your acquaintances is someone who has noticed what you've been doing and has been inspired to take action.
