RIck , May I ask if you rent your property in Tulum and if so what is your percentage on return ?

IF you have a credit score (600+), check stubs, tax returns, buyers meet the 38/48 or whatever the percentage is that is required by all the new laws, you might be able to get about 75-80%.

If that doesn't work, perhaps I should ask him to put in a some percentage, maybe 10-15%.

But the percentage of the pool that's uninvested is less with a bigger bankroll than a smaller one.With direct loans, the transaction is between you and the borrower, perhaps facilitated by a broker.

After you have more than four properties and work a full time job, it is hard for DIY landlords to be able to prioritize leasing during weekdays, etc.As an investor increases the number of properties, the ability to juggle it all without losing days starts to occur and then you can make a decision to get help, go at managing your properties full time, or becoming less efficient.What percentage of property owners  do you think has what it takes to really be able to manage their investment without losing days?

Are there not companies that install the washers and just get a percentage of the profits

They same percentage down as a loan?
