This will be my first time managing a renovation out of state so I wanted to find people who have done this successfullyAny advice you have would be super appreciated, thank you! 

Nothing could be further from the truth.  

Hi @Ross Denman Hope you're doing well.

Does anyone have experience with how much the annual revenue might be?

It seems like what you are planning would be in their best interests so I would discuss it with them first and then make that the impetus to sign a new lease and up the rent.

They also don't know what happens after inspection, well and septic test etc and are often extremely difficult to deal with.

your criteria should be numbers, not a calendar. 

People responded by explaining that residential mortgage lenders are looking for US-based customers, who have their residence, income and assets in the States.How do they view foreign debt?

But my thinking could be off.

@Akil MitchellIf the city has already said the garden unit needs to be deconverted, it's probably best to avoid the property entirely.
