Hey...Charles.
I have 2 properties and renovating the 3rd. Lots of questions and areas for you to sit down and brainstorm...put it on paper to help narrow your focus/questions.
Zillow, rentometer, etc helps with rental rates.
you're not going to hardly rent a property for more than the area brings...but you can certainly rent or less
Are you looking at A, B, or C properties (the initial investment amount compared to the return changes) but then so does the risk
My properties are all in Winston; C properties, but I have paid 20k and less for each. But in the past 3 years I have had 1.5 month of vacancy between the two properties.
How involved will you be...you need to know the condition of your properties and if you don't use a property management firm then the tenants should know that you mean business (it's not personal)
Age, brand, and maintenance history of HVAC, water heater, roof, gutters, windows can be larger expenses you should really appreciate when purchasing
Using a GOOD realtor will help you a lot in learning what to look for.
When analyzing the deal... what are you looking for (turn key properties ...not usually much of a DEAL, but can cut out a lot of time=money)....rehab projects would require another post...but check out the tax card (building value, land value), annual taxes, recent sales ( you may see a trend of purchases/sales), Zillow ( comparisons of nearby properties)
Lots of fun Charles , but proceed with caution!! PM if you think I can help
