Quote from @Carlos Ptriawan:  They believe that they will increase the properties NOI by 45% over 5 yr hold, mostly through rent increases after doing 5K interior upgrades in all 252 units, thus adding 19 million to value of property. how is it possible increasing rent 50% in 5 years period in place where comps and rent is decreasing, this local market is extremely saturated.For me if I have to buy in Austin I would find complex that could give DSCR 1.3 at least with 80% occupancy.if they increase rent 50% then we should do intelligence on their closest neighborhood's rent. 

Figure between solar and not having the car loan, my monthly bills will decrease by $1000.

There are TONS of opportunities to buy properties cheaper and rent them.Population growth past 10 years - depending on your source, you should see stagnant growth, a slight uptick or a slight decrease. 

This is unusual as rents typically dip in this time of year.Rentals - Availability by MonthThe number of homes for rent decreased MoM in September, again bucking the usual seasonal trend.Rentals - Median Time to RentTime to rent increased MoM from 24 days to 28 days, but remained healthy especially for the season.Rentals - Months of SupplyThere are only 1.4 months of supply for our target rental property profile.

See the graph below and notice how DOM increases in the winter months:Again, your idea of offering a commission/fee that decreases the longer the vacancy sounds logical, but in practice is impractical due to factors outside an agent's control.

Several cities have a decreasing population too and the outlook really isn't good.

You can see a small uptick in September, followed by a dramatic decrease this month.And a 5 year chart; the average is $3.05/gal, as of yesterday. 

Since Airbnb fees increase the total charge, either of the following result - (1) host lowers amount charged so TOTAL amount still attracts customers (2) total amount is enough to decrease demand and hence increase vacancy time while consumers find cheaper alternatives either through less expensive platforms, direct with host, or at hotel, or (3) consumer stays home or goes somewhere else. 

If you are truly looking to shorten the loan and decrease the rate, it may make more sense to look at a 15 year option. 

Concerns such as the home value decreasing, 24/7 humming noise, increase water bills, increase electric bills and other environmental concerns in regards to health.
