This extra road frontage now also qualifies my property to be able to be legally converted into a triplex from a duplex.

Living in one unit and renting out the others could offset a significant portion of your mortgage, giving you extra breathing room as the sole income earner.

This is very uncommon, though I see folks posting about HELOANs for investment property.  

Interested in getting some extra income with converting the extra space in the basement into a rentable unit.Basements in a one-family home can be lawfully rented only if the following conditions are met:Compliance with the Housing Maintenance Code for minimum room size.There is a minimum ceiling height of 7 ft.The walls, as high as ground level, must be damp- and water-proofed if HPD determines that subsoil conditions on the lot require it.The basement is occupied by one family and does not include boarders.Every room must have at least one window.The bottom of any yard or other required open space cannot be higher than six inches below the window sill of any required window in the room.

Be wary of the facebook groups as most folks will have a "pitch" or just see the possibility of a transaction.

If so, are your amenities worth the extra price?

And there are a couple of folks in town who are suggesting using installment contracts as workaround, as well.

Easy to do IMHO.Some folks use a tablet with a service but why complicate things I say.

I don't necessarily agree with the folks on here.

But I would charge the extra 3% to cover my costs.
