Traveling healthcare workers often work 2nd or 3rd shift so blackout curtains and a sound machine are nice.

I know people making $20k+ months couch flipping and investing in vending machines.

I'm also a Realtor® and Investor with a solid network.

We also have an ice machine in a beach market to make sure the cooler is always ready.  

I would feel safe using the security deposit on smoke mitigation on turnover which might include kill/paint purchase of ozone machine steam cleaning or replacing carpet etc. remember to account for useful life if replacing.

In general, I recommend fee-only, fiduciary CFP® Professionals - then, within that group, you can filter by those who specialize in real estate in general and exit strategies in particular.

I'm also a Reatlor® and work almost exclusively with investor clients, so this is my area of specialty.I recently began working with Account Closed and his team because beyond just taxes, they also advise and provide valuable services such as cost segregation studies.

Where I'm stuck is whether I should use a metering system that pre-prints a stamp onto the envelop or find a machine that can place a physical stamp onto an envelope (obviously I can't sit there all day stamping).I'm thinking from the perspective of mail that looks to "businessy" vs. mail that looks more personalized for better response/conversion rates.

FX, Crypto, Flipping Houses, Sub2, Gold and Silver, Rare Earth Metals, Day Trading, Bernie Madoff, Vending Machines, Car Washes, Amway, any MLM.....whatever the dream of the day is.In all of them, you can make money, you can get rich, but almost always it takes a lot of hard work, blood, sweat, tears, missed holidays, working on weekends, money, risk, stress.

Best wishes i looked at the 3d printing  the machines are really expensive and the logistics can be pretty tough .. will not work well in super tight building lots or areas you need space for the machine and the big pile of sand :)  but on large lots and small acreage.. and the machine was I think 600 to 800k .. but then you own it..
