I'm not a fan of selling a property that is performing in order to solve a short term problem.

Cash flow is definitely the biggest challenge; both in terms of finding properties to buy that cash flow with a loan on them and just company wide given interest rates and labor/material is up and, at least where I'm at in Jackson County, MO, taxes are way up too. 

I am looking into my first property and have been pre-approved for a renovation loan from a conventional lender.

Owning a duplex at 20 is a huge accomplishment, and it’s inspiring to see you’re already planning your next move.From my perspective, real estate investing is a long-term game focused on building equity, paying down debt, and maintaining stability over chasing short-term cash flow.

@Joel Oh- if you are using a loan to acquire the property - the lender  requires  insurance ....if you own the property  free and  clear - your  choice  but I would still  recommend  insurance 

I am a long-term investor, but I also provide services to long-term investors, so my advice is biased toward that option.  

Rental properties come in several flavors... short term, long term, etc.  

The loft is very successful on Airbnb and people love the main house for long term rental.

@Nick AmDepreciation is a ZERO % interest loan.  

Louis for the hard money loan.
