Our current tenants are moving out soon after 1.5 years.

I recommend checking out Columbus if you’re after appreciation, with its rapid growth in jobs and population, and look into Cleveland and Dayton if cash flow is your focus. 

Travelers in any field usually have streaming TV services so we get SmartTVs with high speed WiFi.

It seems like most all popular screening services like Mysmartmove, Rentspree, etc use the Transunion "resident score" instead of producing actual FICO credit scores for tenants.

Let me just say, of all the tenants I have thought were "great tenants" ... only 10% did I think that after they moved out and I saw the turnover.     90%, I just thought.. oh wow,  all you did was actually pay on time. 

they came and started, getting 50% complete and have been finding excuse after excuse to push us back.

I don't know I got the idea of househack after I force myself to visit all parts of city (within my budget) and try to visit 3-5 open house in a day.

My current primary ( scenario 1) Keep the primary for the life of the loan ( current rate is 4.5 so i dont see my self refinancing anytime soon)current home value 1,150,000Loan amount 935,000appreciation estimate 5% per year after a 28 year hold and the house is paid off I would have a house worth 4,312,000$my current mortgage is 6125$ ( piti) included My second option( scenario 2) Sell the house, walk away with $150 ,000 ish in hand and put that into a low cost index fund Rent a house elsewhere for about 3000$ ish and take the extra 3000$ im saving everymonths from not having to pay my mortgage and puting that money in the index fund as well I ran the numbers on both of these scenarios and doing what I mentioned above would break even at about 28 years meaning my stock account would be worth 4.3 million just like my house would , but the only is that holding a house for 28 year would mean 28 years of property taxes, loan interest ,home insurance and repairs etc whick I calculated to be about 1,200,000$ at minimum which raised my eyebrows to say the least Also i understand that each of these options ( stock market vs real estate ) will have there tax consequences ( long term capital gains) so any thoughts on that would be appreciated as well.  

There are 2 car washes for sale near me and I am meeting with the listing agent today to look at them.

A successful venture involved flipping a 30-unit apartment complex; acquired for $450k, we revitalized it with a $150k construction overhaul, achieved full occupancy, added a laundromat, and subsequently sold it for $950k after two years.
