You are then going to take this contract and market it to a "private mailing list" (because you cannot market it to the general public) for 105K.Keep in mind the general public has already been advertised this house for 100K, Now you have to find a buyer that will never ever find it listed for 100K (from the MLS, a newspaper ad a flyer).

You need to think of and treat the request for a service animal as a request for an ADA reasonable accommodation request which must meet three legal tests:1.

And 2 self-identified FH experts gave contradictory info (one says you can demand it, the other says the financial burden is against ADA).  

Or look into a househack through a duplex, single family with an ADA for airbnb, etc.What are you looking to put down?

Curious where you are looking to invest - whether it be Canyon or Ada County.  

@Bradley Bogdan had some threads with a LOT of details in the past, so using the search BP function would be recommended.also if you go for seniors as customers, please remember to be ADA compliant. or look for the non-profits in your area already doing that. you just provide them approved housing stock.and read again what @Patti wrote: you cannot discriminate, not matter how good intentions....

Start working at 16 saving $25k by 18, invest at 18% in real estate, tax liens, whatever, reinvesting the proceeds and in 48 years at 66, have $102.4M, but ad a little more in the pot over the years and can easily get there in half the time. 

From the ADA website:A service animal is any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.

@Matthew WatsonThe building official is correct about updating the codes and ADA. 

Nice idea and more ADA friendly.  :-)  Thanks!
