If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

I have to do a little more due diligence before I feel comfortable with sending them any of my personal info.

Build a portfolio of cash flow producing single-family homes in a high-cost market with high barriers to entry. 

In order to undertake a new build I would have to personally know the builder and be comfortable with his work.

The sheer number of units amplifies the inconvenience, turning what should be a technological boon into an ongoing headache.While the locks offer attractive features like keyless entry and remote access, the pervasive battery issues overshadow any potential benefits.

The affordability of real estate in the area makes it an attractive option for investors looking for lower entry costs and decent rental income.

I find that the market rents in Cleveland are pretty decent and compared to the state that I live in currently all the 3 major cities in Ohio do have a low barrier to entry.

If you have cash, know that 99% of wholesalers will have low repair values and high ARVs that don't match the actual data or upkeep of the house.Also, ask if this is being daisy-chained, meaning are there other wholesalers or investors in the line between the person offering you the deal and the seller.

I personally would approach this with a self assessment.

like - your own market. or a market a couple hours away that you can spend some time in person in. or where you went to college. or where you like to vacation.
