.- We designed the units for low maintenance (tile floors, only electric - no gas fixtures)- We had 9 parking spots for 6 units so we rented out the 2nd spots

Add on potential electrical main panel upgrades to handle the increased load (assuming no gas service, they'll be cooking and heating with electricity in the ADU), along with drawing and permit fees and you're maybe another $5k. 

Obviously there’s going to be in the economies of scale between how much the policies cost, whether they require gas to get their own policy, and the number of vehicles, etc.Originally posted by @John Underwood:Originally posted by @Clint Harris:I agree John, but there are golf cart rentals in just about every Beach Community that is golf cart friendly, and typically those seem to be pretty high earning individuals.

Perhaps, the heating system is old and inefficient oil heat and you modernize it to a high efficiency unit with a cheaper fuel like natural gas.

With supplying electric, water, sewer, gas, internet/cable, rental property insurance (more than homeowners), furnishing the place including large appliances, and maintenance, there's no cash flow at $4300, but a loss.

Regulations can vary widely, and obtaining the necessary permits can add to your timeline and budget.Utilities and Infrastructure: The cost to install plumbing, electricity, and possibly gas, along with a septic system (if the municipal sewer isn’t available), can be substantial.

Timber deeds are actual Deeds kind of like Oil and gas rights..

But, it doesn't hurt to start with a meeting with your building inspector - He may have already encountered something similar in town and has worked through the issues and made some decisions on how they will enforce/interpret the code as it relates to existing conditions....Hi Danielle - I just purchased a two family in Haverhill that has an attic that is currently occupied...I has an egress and new door and an inner stairway and they made them take out the gas stove. 

If you have to you can get a secured credit card with a $500 limit and you charge 1 tank of gas per month and then refurbish the card.

You might also get a PT side gig going that has something to do with real estate just to give you some gas and food money while you get started.
