How easy is it to get a loan with 30%+ down payment but unstable business income?

This is your first time so I’ll just say being a landlord can really suck and at times has enough drama of its own usually ,so bringing in somebody who’s life is already unstable chaotic and in turmoil is not going to help your situation .

There are a lot of mentally unstable people in his world; maybe he is one of them or maybe not.

I would be more concerned with them being unstable and up and down and up and down (volatile).In many cases not having the rent is BS.They just decided to pay other things before you.Just like people saying they don't have time to exercise but when you dissect their schedule and allocation of time there is plenty of time there.

The job base with lower income tenants tends to be more unstable.

Newly divorced people tend to engage in reckless behavior like excess drinking, partying, "entertaining" guests that are mentally unstable, move jobs, etc.

Some receive a government check and can't afford and apartment, some have temporary jobs with unstable income, some can't get utilities due to past mistakes or can't pay the deposit, some can't afford to furnish apartments, and some don't want the cost of monthly upkeep of a house ie lawn care.

At minimum, the tenant-applicant should have:1) Income that is 3 times the rent2) No eviction in the past 5 years3) No felony in the past 5 yearsBK may be acceptable and tenant may need to put more $$$We go with a POINT system where they can increase their points if...1) they can show they pay their utility bills on time (because if they are willing to miss or be late with their water bill, there's a good chance they are willing to be late on the rent too)2) they have stable employment (1 year, or preferably 5 years or more)3) their income is not based on seasonal or unstable sources (e.g., commissions, child support, cutting the grass, shoveling snow, etc)4) low debts (except mortgage)5) if they submit our requirements readily or they are easy to work with, they get additional pointsThe applicant with the highest points while meeting the above minimum gets the house.

Austin was like a safe haven beckoning (it was also where I was born and spent part of my childhood), a place where I could easily find work and be comfortable.I did look into real estate around 2005-2007 in SoCal and almost got involved with a vendor from Marshall Reddick, but I'm glad I didn't, since that organization went bankrupt and many members ended up losing money in investments out of state during the collapse in 2007-2009.Anyways, I had a hard time getting any traction in LA due to the unstable job market, generally stressful lifestyle and high cost of rent, which made it difficult to save significant money. 

I would have that same mindset about investing in politically unstable nations.
