Lol A good property manager can get labor done for a fraction of the price you can...for example, unclogging a shower drain - $200 if you call a plumber / $50 for 2 hours of labor by your property manager.

They will drain you. 

I always have a plumber inspect, drain lines, etc.

The local spa services charges over $300 to drain the refill, but we trained our cleaner on how to do this and she only charges $100. 

TI...aka Tenant Improvements...your future tenant may want to negotiate different terms for the move in, like a few months discounted rent(this could be on top of the above mentioned vacancy) while they build out the place, or some concession for the Tenant Improvements, if you  have an empty shell it could require extensive work to make it business ready for different types of business, think needing to add bathrooms for a gym(dozens of showers and toilets, lockers, etc) or adding a fully equipped commercial kitchen(walk in freezers, special fire suppression, a few extra sinks or drains) With apartments, I rarely have to do extensive build outs or concessions for tenants, even if I have full on renovation, it is almost always replace the old with same but new, ie tear out old kitchen put new kitchen in same place, same plumbing, just new cabinets, and flooring(if you are at all handy, you can do most of it yourself, or be able to estimate accuracy of bids easily).

WFH is reducing demand for office space, hotels are on the brink of major default because of the COVID scare, and retail is going down the drain.

Just if there is a clogged drain; the plumber will eat up 1-3 months of cashflow. 

Based on my contractor estimates, I'm roughly looking at around $6.5k The property is already rent ready, save for a couple minor things (new man door on the garage, snake some drains, etc).I own a handful of properties but am not an expert when it comes to giving information, but here are the numbers I'm working with:Purchase Price: $55,000Cash In: $12,000 (15% down payment + minor rent ready repairs + misc.)Rent: $800-900/monthExpenses: $538/month (PITI + $120 set aside for maintenance, vacancies, etc.)Net Cash Flow: $262-$362/mo. (26-36% CoC Return)The cons that I'm hung up on are (1) that the home is certainly not being purchased at 75% ARV or anything like that, but then again the house itself save for the two items I mentioned are in great condition; (2) comps in this particular neighborhood are nearly impossible to place... a few years ago these houses sold for $4,000-7,000 each, but the real estate boom has certainly brought some change.

We don't trust people with operating the fireplace and think the pool will be a hassle to maintain and a drain on revenue. 

They rather poop on the front livingroom floor, desroy the cabinets and pour concrete down the drain then sell to you... let alone at a discount.
