I personally happen to believe that market downturns will decrease in frequency over time. 

If demand decreases, it could affect your rental income and potentially make it more difficult to sell the property in the future.Vacancy risk: It's possible that you may experience periods of vacancy, which could impact your cash flow.

See the table below.Renovate to Lower Maintenance CostsRenovation is transforming a property to increase rent, decrease time to rent, and reduce maintenance costs while spending the least money feasible.

Look at all the market reports that are showing decreasing rents in many areas.

Don't lower your standards but a 5-10% decrease may help.

I think the value will definitely decrease during the next year.

I was noticing that going with a 15 year loan really decreases the amount of properties that I would be able to get as far as a good deal goes.

Decrease closing time from 45 days to 30 days, or is that kind of silly?

The only case study would be Portugal and it saw a either a slight decrease or no change in drug usage.

@Richard Raghoo - to increase cash flow, you only have two options: raise the gross income, or decrease expenses.If you are set on sticking to residential, you will have to find creative ways to decrease expenses.
