Thus, I have worked 2 jobs (1  is self employment) for 7 years to fund purchasing a few single family homes locally. 20k is not enough to purchase IMO, that should be your savings AFTER your purchase.

My own personal experience is that a huge stressor has been lifted since I've stopped spending hours looking for and analyzing deals and my index funds/stocks are doing well (just hope it doesn't decline in value when retire from my W2 job). 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

I agree with @Jonathan Greene that the question is vague, so my advice will have to be as well.The short answer: MTRs are real estate, so just like all real estate, any place that can long-term-rent cash flow with increasing jobs/population can be a suitable site to purchase. 

If you’re looking to make real estate your new job and to earn cash now to use and live on like a job, then go for cash flow.

I’m returning to the U.S. after spending a few years overseas, and I’m eager to start my journey in real estate investing.Once I’m back, I have a job lined up with a wholesaling company where I’ll be focusing on buying houses.

A strong “Core 4” can make managing your investment remotely much smoother and prevent a lot of headaches.Also, as you narrow down cities, pay close attention to factors like job growth, population trends, landlord-tenant laws, and short-term rental regulations.Happy to connect with you, and good luck as you jump in!

The article also fails to mention that overall transaction costs can actually be higher in countries where commissions are lower because the agent plays a different role, and due to needing to pay a lawyer for paperwork that agents complete here as part of their job (called a solicitor in Britain) plus VAT taxes and other closing costs need to factored in on top of the sales commissions, which we don't have here, overall costs can actually be higher even if commissions are lower. 

This development, spanning nearly 6 square miles, promises to create thousands of jobs, generate economic activity, and transform the local economy.
