I think the short term effect on rents is virtually zero - illegal immigrants usually live multiple numbers to a home, rather than everyone having their own space like Americans - but longer term there may be some softness at the bottom levels of rentals. i would be more concerned about the lower economic job market than I would be about rental housing.

I run multiple properties in B or C area and I maintain super host status every quarter.

LOL but this route you have only 4 weeks to contact all the sellers MULTIPLE TIMES.- The golden rule in my group is the seller has to have a deal, the numbers work, be willing to sign, be willing to move out no later then 7 calendar days prior to the auction!!!!! 

With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.

I have done several multiple property 1031 exchanges throughout the state for my clients who are looking to scale and improve their investment portfolio. 

I've seen banks be very competitive with blanket loans that cover multiple properties and/or multi-family properties, e.g. 5+ units.Mortgage Brokers (obviously I'm biased) - Brokers have the ability to work with all of the above and can get you to the best lender for your scenario right away instead of having you waste your time with the wrong type of lender.

You can 1031 exchange it into multiple rental properties that will be positive cash flowing in a high appreciation real estate market.

For me, I’ve been testing a few different methods recently, but I’m always looking for new ideas to take my wholesaling game to the next level. 

What worked for me was listing on multiple platforms - Facebook Marketplace, Craigslist, and even local community bulletin boards.

This didn't pass the smell test???
