One more reason why people should stop looking for the easy path to building wealth.Increase earnings, reduce expenses, save, and invest.

And, not confident of the earnings/industry in the area to feel good about LTR. 

I have two options 6.625% 30 year or 6.15% 15 yearI want to invest aggressively in the near future on more propertiesThe loan is only $110k and the monthly payment for 15 year is $563 and $750I will earn 2-3k a month in gross rental revenueThe property is in a declining population areaRecently rennovated, and all major things were relatively recently improved such as plumbing, the roof, a/c, electric, etc.Will require a lot of management as it is rent by the room so I may switch to a normal rental after 10 yearsI'm trying to find what will mathematically net me the most money in the long run.

If you tie the bonus to early renewals, a bad employee will renew bad tenants just to earn a quick buck.

Cost to wait is maybe save couple grand on zoning attorney but could potentially make that up by earning some rent earlier (vs. unused space). 

What is the interest rate on borrowing compared to the rate you are earning, then take into consideration the tax consequences. 

On Airbnb, despite earning Guest Favorite status, I am still striving to achieve Superhost status.

If they get married it will help her earn SS benefits, etc etc. 

I don’t have a loan on the property and hold it cash, but, if I sell it would lend the profits as hard money and earn 10%+. 

If you're earning primarily W-2 wages, interest, or dividends, those attractive depreciation deductions from your cost segregation study will be suspended.Think about it this way: You might spend $10,000-$15,000 on a cost segregation study, expecting immediate tax savings, only to find those deductions suspended indefinitely.Does this mean cost segregation studies are worthless?
