Preferably, you or the seller have a method that can be set to autopay to make both of your lives easier.Hope it helps!

If by real estate business you’re implying you have little or no money to invest but are contemplating using one of the guru inspired methods (subject to, “wholesaling” , fix n flip) to create cash flow, I’d encourage you to do research on the true success/failure rate of people who engage in these endeavors, the amount of money the successful operators spend monthly on marketing, and the real time commitment and knowledge and experience necessary for success.  

Register for guru courses that cover the topics of the BRRR method and subto financing2.

I have my accounts set up in the "Profit First" method by Mike Michalowicz, and so far, things are going great!

The other way is called the Enemy Method, where you go to Airbnb and Vrbo, look at your direct competitors, and figure out how full their calendars are, at what prices, keep a tally of their income, and make a guess as to their yearly gross.

I have found lots of heirs with that simple method.

I'm using the ENEMY method, AirDNA, Mashvisor, Revedy, and Pricelabs for comps and analysis.I was able to select the market and community that is marketed as vacation rental homes and most of the houses are set up as STR.

As your real estate empire grows, consolidating loans into one could offer better terms and streamline management.Overall, your method of buying, living, and then converting properties into rentals is a strong, scalable strategy for building wealth. 

So I made a compromise with myself, instead of putting that $100 directly to my principle, I'm opening a brokerage account that will have $100 deposited into it automatically every month and invested in index funds using dollar cost averaging method.

Google and use the enemy method.
