You can do this 3 ways - decrease spending, increase income, or both.  4) Set goals and stick to them.

Some investors have money and are looking to make strategic purchases, knowing values and rents will increase over time. 

My cashflow will have increased though by maybe $4 - $5k/mth and would have to wait a few months before I have another 20k saved up for another down payment. 

Or see if there are ways you can improve expenses since Cashflow can be improved by lowering costs or increasing revenue.Personally, I dont have enough experience to guess. 

You will need to make sure weekly, monthly, quarterly and annuals goals are met, vacancy is kept to a minimum by either increasing your renewal rate or always marketing, keeping a tight watch on all R&M/capex as well as managing your cash position. 

Install fresh drywall (where it makes sense) and repaint a nice white color.

I am somewhat picky though because I know I can be, as I pass any basic landlord tenant screening with flying colors.
