If we sold the property after two years and it appreciated 3% both years Then I would pay them $500k in addition the to $50-70k that they got in monthly payments which works out to be at least a 22% return in 2 years.I am talking to some lenders, accountants, and realtors and they seem to think this deal is possible.

I say this because you can probably qualify for 3-5% down on an owner occ loan amortized over 30 years with a conventional lender, while most sellers willing to hold the note are typically going to want a higher down payment and shorter terms.

There is also a strong networking of Private Money Lenders at these type of events, which do make building that potential network of funding possible, too.

You can work with a reputable local real estate agent, contractor, lender, and property manager to handle the process on your behalf. 

It should consist of a realtor, property manager, contractor, and a lender. 

hello everyone,  is there any banks or lenders of any sort that would give out loans on a paid off property if the owner has low income ?  

There are a couple mortgage brokers that cater to international clients and will either work with banks or private lenders but it'll be even more expensive.For foreigners, buying property in Mexico is therefore mostly a cash affair.

Investors utilized either DSCR loans or lenders that allowed short term rental income to be calculated for income purposes. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

If that doesn't go well I do have a lender that I can send in a PM that lends to international investors.
