Wholesaling is one of the most challenging ways to start your carrier in real estate; over 90% fail within the first year. 

No one is going to pay more than 4-5k, and even then finding that tenant is very challenging.

but it will still be challenging. 

Finding the private money seemed to be the biggest challenge my friend has had while doing this. 

I have a few concerns that I wanted to get people's thoughts on. 1 - Selling a quadraplex 10-20 years down the road seems like it may be challenging as the market for that type of asset is small.

Living and working overseas can present unique challenges when it comes to securing financing, but there are definitely loan options designed for situations like yours.

One of my rental properties is located in a low-income area, which presents unique challenges in finding suitable tenants.

Developing that trust with someone you don't know may seem like a challenge, but if you approach it correctly, you should be able to achieve a pretty solid foundation of trust.The best way is to talk to others who have had an experience investing with the sponsor already.

The challenge is being liquid enough for acquisition, marketing, and closing to hold these properties for 36 months minimum.Thoughts on what is a fair partnership in this scenario?

The challenge is knowing if the listing agent actually tells your offer to the seller or not.For example, if a distressed property is $650k and you want to offer $620k, the listing agent says the lowest the seller may accept is $645k, but is that actually true or made up because the listing agent wants their commission?
