Just like doubling down on a bet you could lose it all. 

The country's continuous population growth, coupled with its high demand for urban housing, positions its real estate market for steady, long-term price increases.Over the past decade, cities like Berlin and Munich have seen remarkable growth in property values, with an increasing number of investors betting on the continued upward trend.

Best bet though is a local community business bank.. 

If heat goes out in the winter we drop off several units, so they can be placed in different parts of the house - including every room with water like kitchen and bathrooms.We also have dehumidifiers, carpet blowers, shop vacs, puddle-sucker pumps, extra hoses, extra sump pumps with battery pack, squeegees, and portable AC units ready to deploy. 

I’m not a betting man.

Quote from @Brandon Foster: Hello Ryan,STR is do able in the north county area but there are a lot of rules and regulations.The city of Oceanside right now will not allow anything STR unless it’s west of pacific coast hwy.This is changing a lot too so you need to be aware of that in your plans.Carlsbad is super strict too but there are some condos that are still available to do STR in.Medium term rentals are as safer bet but way less profitable.

An experienced broker with lots of choices at the palm of their hand is probably the best bet.

You can talk to the bank about a loan; however, my bet is they will want some form of contract and scope of work and will only pay him at set milestones.

If they have money and can compete on pricing, brokers will be the best bet.  

I'm betting he'd drive to that area.
