These costs would eat into your profits.The case for sellingEven at $125/month, your cash flow is slim, and any unexpected expenses could turn this property into a liability rather than an asset.

Unless you are confident in estimating the renovations needed, I would highly recommend getting a contractor's professional opinion of the rehab costs.

First, estimate what the renovation would cost, how long it would take, and how much extra you could potentially sell the property for once it’s fixed up.

However, after receiving the survey results, I discovered that the house is located less than 1 foot over the sublot line (see attached image).Here are the options I’m considering:Rent the current house for market value (~$1,500–1,600/month) and convert the detached garage into an ADU to rent for ~$1,000/month.Relocate the house to split the lot, then sell the newly created lot (~$100,000) while renting out the existing house.Relocate the house to split the lot and build a new home on the second lot.Demolish the current house and garage, split the lot, and build two new homes.At this time, I am uncertain about the cost of relocating the house.Questions for the community:Has anyone faced a similar situation?
