However, you can get loans that are based on the performance of the rental and not your personal income and debt.

Renting part of the home after conversion provides additional income and deductions.This post does not create a CPA-Client relationship.

Could you put it on a CC and pay it off within the billing cycle with either your income or selling some stock if absolutely necessary?

My recommendation would be different if you were a high-income earner or if you wanted steady equity growth.

BUT...if you're American and can still get loans in the US (the silver lining of having to still file US income taxes while living abroad), then why not use leverage?   

Income Snowball, a system of investing in which a person can create self-sustaining passive income).

Income from leveraged real estate or active business income.

Not a lot of our competitors offer this but it's something we can consider (but for us, it can't be in a rural area, the loan amount must exceed $150k, if we're using PadSplit income (or STR/MTR income) the max LTV is 75% and the down payment must come from your own funds). 

Well, STR can work well for people who own a vacation house for personal use, and just want to generate some extra income when not in use.
