Buying a property with unpermitted attic expansion

[Ranga Ramanathan]

Hello all thanks for reading I am looking at this 3 bedroom 1 bathroom single family residence in a solid C neighborhood it has a really good rental return little over 1% rule. The problem is public records say this is a 780 square foot 2 bed one bath but at some point they finished the attic to add a 400 square-foot livable space. The work looks very professional you can't say that it sticks out I don't plan to do any major Reno at this point that will require any kind of permit but I do have a plan to add a bathroom to the finished attic area sometime in future to add some value. Would you buy this property thanks for your suggestions. Sorry if this is a repeat post my previous post didn't appear for a while Ranga
