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?

So like I am not going to run out and buy a bunch of lots in Lehigh acres or coral gables FLA which is saturated with new builds and un finished new builds were the  FOMO got going big time and builders have failed to execute and left investors high and dry.

Think multi unit residential, commercial properties, or purchasing houses “subject to” existing mortgage.  

There are actually THREE kinds of subject to transactions1- subject to existing mortgage without lender approval2- subject to existing mortgage WITH lender approval3- subject to existing mortgage as part of a seller financed wrap around mortgage.with #1 and #3 it’s in everyone’s interest to utilize a third party servicer, who collects and then distributes payments.  

Also It seems that in my city this doesn't exist with a duplex, triple etc.. 

For existing properties, you must make substantial improvements (equal to the property’s value, excluding land) within 30 months.Ensure the duplex qualifies as an OZ investment and complies with QOF rules.

Check with your State Historic Parks Office and get their opinion to see if it would be likely to get a determination of individual eligibility.If it doesn’t meet individual eligibility, does the subject property exist in an area that has historic fabric?  

I could be wrong but I am unfamiliar with any products existing.

Scammers do exist, and it’s smart to verify a lender’s legitimacy before moving forward.Check Reviews and References: Look for reviews on trusted platforms like BiggerPockets or Google.

It sounds like you have an un-permitted unit, which is essentially always a risk since there has been no notice to the AHJ that it exists and they can therefore initiate a code case to have it removed in most cases.
