Who knows though...maybe immigration will loosen up, birthrates spike from the boom we're seeing, any number of things could happen to keep values high. 

But it does happen with immigrants who do not speak English and are reliant on third parties to translate and sign things for them.

They have a good idea who pays quickly, who cheats on permits, who hires illegal immigrants, who likes lawsuits, who inherited the company and is riding on "Pop's" coattails, which companies are staffed by stoners, who is cheating on taxes, and who can run a job and get work done on time. 

What if it is the case the tenant is a relatively new immigrant and does not have many previous landlord references ?

There are also undocumented immigrants who may not qualify to purchase their own home in this country.

Always a shortageRising populations in sectors such as Immigration, Millenials and Baby Boomer generations suggest ever-increasing demand in future.Reliable secure returns when purchased/managed correctly.Easy to understand fundamentals.Value-add options are easy to implement.Economies of scale = 1 roof, expenses can be shared among tenants and savings made.Multiple sources of income = Decreased risk in case of vacancy due to multiple tenants paying.

We went to tour the area and it's such an interesting pocket of mostly Latino immigrants living in densely populated condo buildings within a 4-5 block radius surrounded by large and expensive homes on the water. 

They want to see 90% to 100% occupancy.Secondly if you could find a private lender they would not give out a larger secondary loan subject to the sellers first mortgage.That is a very weak position to be in.You have to be really careful in smaller towns.The fact that the seller stated it gets better with temp workers shows this might be a one to two company economy town.You want national businesses there along with mom and pop to prop up the economy.You do not want one to two big businesses and if they leave the town becomes a ghost town.I have seen this happen.There was a town where the main employer was for carpets.Many immigrants worked there and rented apartment buildings.The state passed a new immigration law and many fled the area and with construction down not as much work could be found.This led to 100% occupancy and rents going up to 70% occupancy among all the apartment buildings and rents going down.So it is critical when looking at these types of deals to understand what caused the problem and where does the town look like it is going long term.If you estimate the town will take 10 years to cycle and your goal is hold for five it won't really meet your goals plus can you harbor having a problem property until it up cycles again??
