It all cash flows like a gold mine until the roof needs to be replaced, the main line goes, or you get your first turnover bill and need to upgrade a kitchen. 

Your PM replaced the water heater because it was leaking.

So I'm thinking a good target will be around $30k/month to replace both of our incomes and live how we want to live, respectively. 

I did have to replace windows.

I figure the ones over 50 or 60 years old have already had all the big ticket items replaced.

So, you either need to plan the repairs into your operating expenses so when it's time to repair/replace something you're prepared or you need to repair/upgrade at your entrance in order to put much less away per month for CapEx.If you need a CapEx calculator or a cash flow analysis calculator check InvestingTE.

Quote from @James Wise: Quote from @Duane Williams: We’re a family-owned fix-and-flip company operating in San Antonio, TX, and Northern Virginia, managing everything in-house—from wholesale acquisitions to rehab & construction (with our own project managers and crews) to listing & selling through our licensed brokerage.

I I believe that real estate investing is a wise way to create long-term wealth for the family and my husband agrees.

And after you have sent 15k on downpayment and closing costs, you have 10k left, which is just enough for one HVAC emergency replacement and some paint. 

This not only helps me spread my money wisely but also eliminates the need for me to handle the day-to-day management tasks or hire someone to do so.Currently, I am investing in a mobile home park, several apartment complexes across the United States, and even a manufacturing plant.
