They found it out, andI had to go to the planning board and zoning board, hire an engineer and architect to make the fourth unit legal.In my opinion, the realtor should have verified the zoning, and if you used bank financing, it's pretty rare for the bank to miss it as well.You are probably going to have to hire an architect to draw plans and to get it approved as a triplex.I wish you luck.

Hey Helena, I know we've already chatted but you should check out this BP thread about us:https://www.biggerpockets.com/forums/311/topics/1184140-plan...

You're in the right place and now is the time to focus on education and planning.

A good real estate accountant can save them thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend that they find a tax accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.I would also recommend that they look for a accountant willing to work with them throughout the year, who can help them strategize and who is responsive when they want to know the consequences of the financial decisions they are making throughout the year.Good luck.

I think the ultimate situation for what I described above (not the plan, but a possible outcome) could look like this:Rent main house by the rooms while constructing ADU.

If you're planning an open house at a vacant listing, know that you've just let the general public know that it is just that - vacant.Better safe than evicting/repairing...

The bank will put a hold on them, so you can't just draw them out, so don't plan to need them for a while.This will cost you an appraisal on both properties to be performed by that lender. 

Quote from @Jed Butikofer: Quote from @Jonathan Greene:I think it's great that your plan for next year is just one investment property.

You'll need either a POA or schedule an appointment at the nearest U.S. embassy or consulate for document signing - and you need to plan this well in advance!

Seller financing is a good way to start if you are looking to sell to your current tenants, other than that, you will need to run into a proper plan why you will need that and how long will it take you?
