If you're only making $1k on a $100k investment, a 1% CoC is probably below what you could find in other investment strategies and your 1% is very high risk because 1 water heater gets you negative.

I want to scale, but not sure how to develop my strategy.I have a $200k HELOC and excellent credit worthiness and high income from my day job.

My only hurdle is the fact that I don't know the Real Estate Investing industry that well, so I don't know where or how to find the right documents for my wholesaling transactions.I've began generating pre-foreclosure leads, which I am able to filter out just ones with high equity, owner occupied, and no auction date, yet.

This is because they didn’t budget properly and rent wasn’t high enough to cover actual expenses (repairs and maintenance, cap ex, vacancy and loss, tenant damage and turnovers, etc don’t expect to have any money left over after all of these expenses are accounted for if the rent is less than $1,500/month). 

I dont have any experience in this market but have looked into it a little bit, I know that you can get the houses pretty cheap there but my concern was with the long term appreciation - I dont believe it is a highly desirable place to live and so there wont be much appreciation -however that is just my opinion and I really didnt look into it much,  I think it would be a cool place to live as I go to Monterrey all the time, but its hard to say. 

@Ramada Evans your approach, not doing your own research and just asking a bunch of strangers for general advice, has a high probability of ending badly. 

Your scattered approach is going nowhere fast (analysis paralysis) and is highly likely to result in someone taking advantage of you:(Recommend:1) Figuring out what investment approach suits your skills & risk tolerance2) Determining where in the US to apply your chosen approach3) Learning everything you can about that market4) Networking & building contacts & team in the market5) Doing a "test" investment in that market to make sure your expectations are met6) Investing more if your expectations are met.-- If not, go back to step #1 as you many have chosen the wrong approach!

Due to the high turnover and increased vacancy throughout the country I would raise the rent, put them on a month to month, and be thankful that you have a paying tenant.

However, a lot of condominium communities have clear guidelines on rental restrictions that often prohibit leases less than 6 or 12 months.Before paying for a really nice high-rise, please make sure you will be able to monetize it the way you'd like prior to purchase.Best of luck.

These items will vary from DSCR Lender to DSCR Lender and can also be determined by things like your credit score, property type and its DSCR ratio, etc.  3% origination cost is very high for DSCR as well unless you are essentially "buying down" the interest rate quite a bit (trading fees for a much lower rate over the life of the loan)I have also been told by multiple people that I should create an LLC or Trust.
