To clarify, I had initially put the property under contract but had to back out of the deal due to negative inspection results, specifically related to foundation issues.

Most of the sponsors do not have full real estate cycle experience but a relatively smaller number do.2) Most of these deals are protected under nondisclosure agreement.

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Not sure, from what you're writing, what the benefit to the borrower was in refinancing, but there had to be something; cash out and lower rate are two that come to mind. 

It’s a win-win: investors get the capital they need to grow their portfolios, and lenders earn competitive returns with a relatively low-risk investment.It’s worth considering if you're looking for more funding options or better returns!

Doing a cross-check on that gives you more room to relatively negotiate.

The power of leverage is one of the main benefits that distinguishes RE from other investment choices, and the refi is where real wealth is made.

Also, in this case, it will probably be cheaper than renting and I will also enjoy all the long-term benefits of owning real estate. 

IMHOThere are more international students staying, I've seen it where I work (at a university), but many of the newcomers are not students and a country our size can't handle that many people in a relatively short period of time. 

(I have a special needs trust for my son so have dealt with the complexities.)My bigger concern would not be your liability exposure but doing something that could potentially endanger the support benefits your brother is entitled to.
