Couple thoughts:
1) Buy a 2-4 family, live in one unit, rent the rest for cashflow, but more importantly - experience!
2) Keep in mind at least 95% of agents are CLUELESS when it comes to working with investors. Most only deal with owner-occupied properties. Ask how many rentals they own before dealing with them.
3) Learn the differences between investing in Class A, B, C & D rentals. See below:
In our OPINION (always verify yourself!):
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.
Tenants: Majority will have FICO scores of 680+.
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.
Tenants: Majority will have FICO scores of 620+, some blemishes, but should have no evictions in last 5 years
Class C Properties:
Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation. Can try to reposition to Class B, but neighborhood may impede these efforts.
Vacancy Est: Historically 10%, but 15-20% should often be used to also cover nonpayment & evictions.
Tenants: majority will have FICO scores of 560-600, many blemishes, but should have no evictions in last 2 years. Verifying previous 2-years of rental history very important!
Class D Properties:
Cashflow vs Appreciation: Typically, all cashflow with zero or negative relative rent & value appreciation
Vacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.
Tenants: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.
Make sure you understand the Class of properties you are looking at and the corresponding results to expect.
