I am reaching out for your expertise regarding a situation involving a seller from who I purchased a property subto an FHA loan in March of last year.

That being said, I had to translate a lot of documents on my own for the loan process, so there was more effort involved.

Sure, I could look for a higher paying job, but I was wondering if anyone has any creative short-term methods to improve my ratio.

I feel direct mail is another great method.

As mentioned above get involved locally. 

Specifically, I am interested in learning more about syndications, working with lenders, lawyers, CPAs, and other professionals involved in cross-border real estate deals.

There is still some paperwork involved but significantly less than traditional lending institutions.  

One of the biggest challenges for everyone involved is being on the same page about the actual time required for maintenance.DIY landlords rarely properly track their time when it comes to property management in general - tracking their true time invested in maintenance is where they perform the worst.Investors that hire PMCs are rarely any better at understanding the true amount of time maintenance takes.

He uses poorly thought through methods, I've listened to his "methods",  Thus, he has the high amount of  Due On Sale called in a short period of time. 

I hope you found the Google reviews before getting involved.
