Also, now that I have kids, my parent's IQ has suddenly shot way up in my eyes :) As for what you could say to convince them, it may be best to show them rather than tell them, and you can show them through your 1st primary residence, then one property at a time after that (read up on BP about "house hacking") ... this is a good strategy to start with anyway, regardless your parents.Finally, understand that nobody in life gets to do 100% what they love and are passionate about 100% of the time, regardless of if you start with a traditional job or start your own REI company, there are going to be big sacrifices and times when you'll have to "suck it up" and do some things that aren't at all fun or fulfilling as a means to an end.

Out of curiosity, your management cost is $0 due to a long standing tenant fulfilling that role.

I learned that your ambition and desire to fulfill you Dream should be bigger than your pride.

The tenant screening should include a full credit check, criminal background check for felony at the state and federal level, homeland security check and sexual predator check.  

You could take the same approach but make sure you genuinely believe in the cause and are doing it for the right reasons (i.e. helping further the cause’s mission) vs trying to grow your biz, otherwise it will fall flat and won’t be fulfilling for you.By doing these simple things, you can build an investor network in your city that is perhaps stronger than any other network.

Without the fulfillment of the contingency, there is no sale.Long delays by the lender in responding to the contract for sale can be very frustrating for buyers and sellers.

In most states an email is considered to fulfill the "in writing" requirement for cancellation of a contract.

I see the rent to property price ratio is very low, and I don't think it would be easy to persuade someone to fulfill our 70% rule around here, I don't know. what are your thoughts on this?
