I think the revenue would be a little better than renting by the room, but you'd have to research your area.

PLEASE accept that if these are your biggest problem you are golden.

My rule of thumb when analyzing rentals is expenses will be 50% of revenue  and that is before any mortgage. 

We have properties that have machines that we own in our laundry rooms as well as properties that have machines from a vendor.It comes down to whether you have an existing contract in place (these tend to be long term - 10yrs and often inherited) , how much use/income you anticipate and whether you are willing to take on the maintenance of the machines.For in-unit machines, you can buy and rent them out to the tenants or you can partner with other vendors who will do a revenue share.Hope that helps.

One of the biggest reasons he recommended this is to preserve ceiling height in the basement which is already a bit shorter than I'd like.

My biggest concern on the property is getting renters willing to pay market value rent.

One of the biggest mistakes I have seen people run into is racking up "good debt" without adequate cash reserves. 

For example the biggest mistake made with BRRRR is probably underestimating the rehab budget.

One of our biggest hurdles is going to be that everything is selling fast and for top dollar.

I think what's happening is that the bank is looking at my other investment properties as liabilities rather than assets, and they are considering the mortgages that I have open there but not the revenue coming in to pay them off.
