I’ve seen many people get creative offering many projects like car washes, propane, u haul rentals, food, etc.

This coud it be completed with machine learning yes, but it is the sales agents that push data toward the platform.

If you have a back to back turn around, how can you do in house laundry with 2 - 4 loads of wash and dry and fold in the 4 hours between check ins.

If so, what are some good inexpensive arcade machines and/or game tables the renters like?

If you can rent them, then they are a huge money maker.I don't recall what we paid for it, but let's say $10,000 and I use it 75% for biz.So depreciation is $7500 (assume 30% tax bracket, tax reduction $2625) That is a cash inThen rental say about 75 days @ $250/day = $18750Less costs (gas, repairs, service, insurance etc, which will also be a deduction from revenues) = $5,000So Yr1 you are at $16,375 and your machine is all paid for and then some.I don't have a garage so it is parked on the side of the property.

I think the rule was more meant for manufacturing/machine shops given a few of the examples in the regulation.

Maybe keep an ozone machine running?

Exterior upkeep is essentialHave enough machines for laundry timeslots to not matter, but great idea!

I've sold properties to investors who hold portfolios and for lack of better word the properties are all trash and then I've dealt with some who have a well-oiled machine.

That may sound pretty good...until you discover that their net worth is decreasing at a rate of $2 million per year, and they've got $100 mil of adjustable rate debt on a portfolio of D class properties that forces them to work 80+ hours per week just to keep the whole thing afloat...Investor B tells you "my net worth is $1 mil" --to many successful investors, that sounds like a relatively insignificant net worth...but, investor B owns a portfolio of A class properties with zero debt, professionally managed, their cashflow is $500k per year, their net worth is increasing at a rate of $1 mil per year, and they only have to work about 1-2 hours per week to keep their machine going.Personally, I'd MUCH rather be investor B than investor A, even though investor A's net worth is 10x of investor B's.So yeah, tracking net worth is advisable, but it's only a small part of what an investor should be tracking and modeling, and net worth alone might not be very indicative of an investor's success.
