If the property is vacant, you will attract a larger pool of buyers as not everyone looking for a house wants to use it as a rental. 

If I owe $350k mortgage and I take out $100,000 HELOC and spend it on say a 6 month CD,And then I sell the house for $700kI would only have $250k profit right?

Keeping my eye on the worst houses in the best neighbors that need some reno that I can turn into STRs or LTRs.

Would add Sub 2 & Out of State House Flips. 

I get a lot of questions about housing vouchers and how you determine rent amount allowed.

The rental market is expected to stay flat or soft through 2025, then is estimated to start appreciating again once the new supply of multifamily housing reaches traditional occupancy levels.

Hopefully you already worked this out.Aside from HML, there's also an option to do a live-in-flip, where you live in the house for a year and renovate it slowly.

This cultural preference for renting creates a steady demand for rental properties, ensuring reliable cash flow for property owners.Additionally, many Germans face a significant shortage of affordable housing, particularly in major cities like Berlin, Munich, and Hamburg.

However, it will be hard to make the numbers work if you are borrowing 100% of the purchase price.As others have said, house hacking is probably your best option right now.

There is a single family home that was divided and one half has been rented and an ad on small "house" that has also been rented mostly long term.
