If I were to sell and build the two smaller houses, I could likely fund them enough from my gains on the current rental (and a little out of pocket) so they also cashflow ~$300-400/mo each.So, at the end of the day It’d be a wash or a little loss, cashflow wise, on one house and I’d gain ~$300-400/mo on the other house.

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.

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.

Then we wash all hard surfaces with vinegar.

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.

If you owner occupy and rehab the home around you great while looking to sell at the 2 year and a day mark or later (to wash up to 250K as a single owner occupied/500K if married).  

We washed the concrete with a garden hose and chemicals.

So, at the end of the day It’d be a wash or a little loss, cashflow wise, on one house and I’d gain ~$300-400/mo on the other house.

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..
