I also own and operate a business that provides water submetering for multi-family properties of all sizes.

Eviction should be the ABSOLUTE LAST OPTION.

Either way, I'm glad it's being more recognized as a good housing option. 

The rent by room was managed by a company which I no more trust and started exploring other options 

The only situation where I've seen it become successful is around the universities, specifically temple because of the amount of multi inventory.

Are there options for assuming the existing mortgage and financing the remaining balance with another mortgage?

These types of tenants often do this because they don't want to save in advance, so they take the rent owed to you and use it to put down on their next home.Recommend you do a better job of communicating to the tenants that you will pursue every legal collection option if they don't pay last month's rent.Also, why are tenants NOT staying with you?

Investors are limited in repercussion options, as there are few attorneys willing to specialize in the nuances of international contracts.

There are some that don't charge interest on the money for the rehab until you're reimbursed from the lender on it.There are other lending guidelines out there such as: -Any level of investor experience-Funding in as little as 10 days-Credit scores as low as 640-Non-owner occupied Single Family, Multi Family up to 4 units property types-Purchase Loan Amount – up to 90% of Cost (depends on area you're purchasing and if you have a higher credit score)-Rehab Loan Amount – up to 100% of Cost-75% maximum after repair value-12 to 24 month loan term with Interest Only payments.
