Seller says both have been very low maintenance required for the past 30 years, only occasional leak repairs.

Then I would get occasional emails from the VRBO bots whose algorithms told me I was "in danger of losing my listing privileges" because of my "low conversion rate" - as if somehow it was my fault that 1000 people looked at my property (which I did not believe), 5 people inquired, and only 1 person (if that) actually booked. 

It’s a hot, subtropical country with occasionally oppressively hot weather during the tourist season and seven months of consistent heavy rain outside the tourist season.

Plus will buy and list occasionally for others.

Occasionally I will get one that I can BRRR although they are hard to find right now.

My listings were in Craigslist, Facebook, and the occasional poster at the grocery store.Have people really become this much less considerate?

Yes, the lease says 48 hours but the intent was just that you would have occasional visitors.

Occasionally I'll let them draw early if they're tight, but only for work that's been completed. 

Folks, April of 2058 is not all that far away.Of course this would never happen, people have to pay taxes and eat food and buy diapers and indulge in the occasional lap dance, among other things.

On the flip side larger units of properties generally have professional managers in place with excellent books and then occasionally you will have a few sellers that self-manage and keep poor books or a bad PM company.I have seen tally's of 25% to 60% in ranges on the 50% average used.I tell sellers when I list there property that they need to think about the buyer.Even though you manage the property and save 10% on property management doesn't mean the buyers will not use one.Example: Property at 100,000 NOI is 1,000,000 at a 10 CAP but put in management instead of self managing to reduce by 10k in costs now the property to achieve the same 10 cap is at 900k sales price.I find this happens often in the 10 unit to 30 unit apartment complex range where a seller can manage themselves.Anything above that in unit size usually a PM company is in place.So I tell sellers we have to price according to what the costs will be to the majority of buyers looking to purchase your property.As other investors have told me.Corporations say the seller does a great job with costs but our managing structure is different so we can't offer that price.Others say they can't manage the property as well as the seller can so have to offer based on more conservative numbers to give themselves a buffer.So as others I use the 50% equation as a quick reference and nothing more.When I get into cost analysis I ask myself if the seller has been cutting out trash pick ups,termite maintenance plans,and defering maintenance and improvements to boost cash flow on paper.
