You would need to show a proven track record and document how you can ramp up your existing model and achieve acceptable return with relative assurance.

When I first started I jumped right in and the ONLY thing that saved me was the market, but I can assure you if I started now the way I did a while back I probably would have gotten burned.

If I get one qualified response from the ad, that's obviously not enough interest to run out and buy a house like this with the assurance of being able to rent it - how much of a response would you want to see to be confident about renting a unit at a certain price-point?

I have a 401k that will allow me to assure them there is a exit strategy and I will get a notarized letter and or a contract drawn up.

I can understand your feelings but I can assure you that we're not too big to pay attention to ways to save investors money. 

For example if me and someone else from USA invest 15-20K each in buying and maybe flipping house, is there some tool or some legal assurance where I can be sure that my 15k is safe invested?

I assure you that you will be more successful being EXCELLENT at 1 thing than being good at several.

Remember even if you don't know about something and it comes back later guess who is responsible for knowing all of this, you the realtor.Here are the most frequent claims made against realtors, fraud, negligence, breach of contract, breach of duty, misrepresentation regarding floods or leaks, misrepresentation regarding the value of property, misrepresentation regarding the condition of the property, consumer protection act, bodily injury, property damage and earnest or escrow disputes.How do you protect yourself as a real estate professional, take a look at what I offer as in legal service, some people compare this to insurance, I say its more of an assurance so you can worry less and live more.

This assures that they'll gradually get their money back AND make solid returns at the same time.

If walls are sealed properly, then nothing that was on them can leak out; I have never heard of replacing sheetrock but can assure you that my property was as bad as it gets and yet my treatments worked just fine.
