Second, I'd like to manage each property to make some cash flow to cover my 2 biggest expenses which is housing (covered by house hacking) and transportation.

Fully insuring you properties and adding a umbrella liability policy will probably cover you 99% of the time8.

For example, a buyer may be willing to purchase a property needing repairs, take on existing tenants, or be willing to cover some or all the closing fees.Of course, selling in a hot market means you may pay inflated prices on another property.

If you want to know if it will affect their portion of rent, this is usually based on 30% of their income and Section 8 covers the rest.

So logging those conversations, meetings, or site visits you’re involved in will cover you.Using a spreadsheet to track everything can make life easier, especially if you’re logging hours often.

To depend on the rates to drop substantially to cover refi cost is a gamble.

Some areas may still be good to invest in even with global uncertainty.Interest Rates – Try to get a good mortgage rate now, as waiting for rates to drop could be risky.Cash Flow – If the rental income covers your costs and gives a profit, it's a good sign to buy.Long-Term Thinking – Real estate tends to grow in value over time, even if there are short-term changes.Rather than holding off, look for deals that make sense for your goals now.

Not so fast, you didn't cover equity skimming or dealing with a "protected class" or  . . . . . . . . . . . ;-)  your right because I dont charge to consult for sub too.. 

Make sure you cover the roof, windows, sheds, landscaping-everything.

At this point, I would recommend having a line of credit to cover these things so you don't have money sitting in the bank doing nothing when it could be put to work.I have 33 units, no debt except for mortgages, and excellent income.
