It's great you are starting real estate investing at such a young age.

Also, depending on the age, layout, etc., of the property it may be better to establish a RUBS system or implement a flat fee. 

I have placed the home age into my consideration.

The website talks about younger family’s and I know someone who lives in the community so there isn’t an age restriction.

Some have been on the market a long time simply because homeowners are aging and want to scale down to something more manageable.

Here is what you will need to run numbers:Price, Rental Comps (be conservative), age of properties, average vacancy (look at the rental comps and see how long their average DOM is, add more time for turnover), property management expenses, age of components of house (used to calculate cap-ex), any HOA fees, taxes/insurance/financing costs.If you can get estimates on these you can run them in the BP rental property calculator tool which will tell you everything you need to know.

FICO gives more credit for payment history and account age.

Obviously this depends on age, condition, location etc., but that is the range nonetheless.

The variable for me is the age of the building, but I'm confident in the growth potential.

Ensure that your cash flow expectations take into account aging systems, and2.)
