.: I'm not aware of any requirement for this.I do provide an application because it has a lot of information necessary for tracking the individual: social security number, driver license number, previous addresses, etc.When you take over an existing renter, I recommend you figure out how to get the entire file from the former manager/landlord.

You can build in sound proofing, but honestly I'd go with 2-3 floors for each so you don't have the tenant downstairs complaining about the one upstairs walking around at night.For costs-it could be more or less than new retail-depends on finishes of each. 

My sentiments exactly you're on the moneyI feel bad for individual who don't surf social media about companies like this that prey on individual who believe this get rich scam.thanks for your insight.signSign. at your own risk....... . 

Are there any social media pages they are associated with? 

So, real estate agents may do it part-time, but rarely do they do it well.Recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Ask for proof of funds, more information about the buyer, etc.

Also get proof of paid invoice for your records, too.2.

When speaking with the attorney, show him the letter of the other unit as proof and start the eviction. 

Here's a record of the non-payments (judge: but there is nothing on this bank statement) exactly...that's my bank account for the rent, and it has not been paid.....so then the judge will turn to the tenant and ask for proof of payment. 

We are not white knights we are in business to make money on RE  not a charity or social workers.. so we do want to keep this in perspective you did what you needed to do so you could make a profit bottom line.
