Mortgage free.c) buy home with already having converted room/bathroom/basement.

We are in the process of purchasing a duplex in Moscow, ID and want to convert the property to separate parcels. 

Would it be worth it to convert a multi-family from window units to HVAC?

My work around was to convert a free standing garage I had into an ADU which will stay on the lot with the old house thus keeping it RSO.Sorry if that was not succinct, its just REALLY complicated.

The loan began as land loan under my name that would be converted to all-in-one.

This would also mean that I could convert all the units into STRs.

Interestingly, they've recently negotiated a re-purchase price with us IF we bring new funding to the table.The rehab is required for several reasons: (a) correct the damage the bank has allowed to happen to the property improvements these past few years (known problems include completely destroyed pool makeover; wild animals living inside the residence; flooring missing in sections of the rec center building; destruction of the decorative main entry gate mechanism; lots of dead landscaping; as well as latent defects not known to us such as working plumbing, HVAC & water services) AND (b) expansion & upgrading of the accommodations (converting the private residence to a 2-story lodge with the restaurant/bar, reception/check-in, movie room, public restrooms, gym/sauna/steam room/massage therapy room; enlarged pool & deck area with climate-controlled cover for year round use; conversion of former restaurant/bar building to a general store selling venue collectibles & wearables, selected pre-packaged foods, sundries, RV & camping items, bagged ice & a propane refill station; construction of a free-standing event center; free-standing cabins; enlarged & upgraded RV park with its own small restroom/coin-op laundry building; outdoor activity areas; new landscaping & fencing; new parking area & entry drives (personal car & RVs).We know our target audience having created and operated the former version of this resort for almost years creating an initial membership base numbering about 1,100. 

We converted an existing extra room into a brand new looking laundry room with washer and dryer hookups.

You're speaking my language ; ) We've been buying and renovating properties that have ADU potential for quite a few years now and about a year and a half ago converted one of those ADUs to an MTR and it is working out great.

Complete remodel and converted to duplex.
