More secure and stable than an STR (also less competition) but you aren't in the red like you'd be with an LTR. 

And yeah, exhaust fumes fo any kind, yeah, let's get ride of em when we can just because we can.

It's less than an hour of time, and if their prices are fair, they are respectful, helpful, positive and can build a good rapport with me (and they check out) they will get business from me....even if they need to give me 2-3 more bids before we find the right project.I don't think a GC who's int he business of doing $10,000-$50,000 renovations should be charging for his bids.

@Linda Pasas you'll want to look in to it yourself but my understanding is that an umbrella policy kicks in after your primary policy is exhausted. 

@Vikram Jayaram  I think a lot of people get hung up on the idea that a new home is less maintenance than an older one, and while that might be true for a few years, most homes start having things break at 8+ years in (sometimes even less), so it wouldn't be long before you are dealing with maintenance calls for a newer home as well.

I also didn't see these sort of numbers on AirBNB, but the broker claims that there isn't anything like it in Miami Beach and it's like an alternative to a Hotel rather than an apartment due to all the amenities etc.Condo price crash in Miami Beach, is that really something that is being talked about? 

The SFR + ADU is worth less than a Duplex because the ADU is viewed as an amenity rather than an additional unit so your appraisal will look for other SFRs with ADUs and provide line item adjustments for homes with and without ADUs much like having or not having a pool or a garage.

If it’s a 2M property than an extra $100k might kill the deal?

Recommend it be serviced and inspected by a qualified HVAC contractor when weather permits.The exhaust flue for the furnace enters the masonry chimney and has some gaps around this penetration.

A few shingles you're done in less than an hour.
