Cash makes low-income people who know their aging house has problems lose their minds.

One of the topics I hear about is the age old topic of to leverage or not to leverage.

You will find many ways to invest at any age.

Neil, I believe the age limit as to a toddler is 3 years old, babies are really counted, you could have twins, 6 months old staying in mom and dad's bedroom.

I totally understand the struggle of trying to invest at a young age..

Also, the age of the homes is old. 

Here are some more:- What is included in rent (are you paying utilities and yard care or is the tenant)- Vacancy rate (Is the area desirable and tenant base stable or are you going to be re-renting every six months)- Age and condition of property which affects capex (are all the mechanicals new or are you facing major expense like a roof or furnace)- Expected appreciation (will you be able to sell it quick for a profit in 10 years or will you have trouble giving it away, which is a real problem in some areas)- Financing terms (owner financing or bank, money down required, interest rate)- General class of the property (in general C or D class tenants are way harder on a property and invite more problems than A or B class, which affects your operating expenses)

Previously to this I was a Mixed Martial Arts (MMA) instructor and fighter, but decided to change courses at the young age of 22.

Being "near" in the sense of being in the same town is really important as parents age, but a little distance can be important for your  mental health.

of course, repairs may eat away at that margin, so depending on the age of the building, you need to factor in a minimum of 5% for maintenance and 5% for capex.  10% across both may be reasonable for the first 3-5 years if it needs new things like kitchens and baths to be refreshed.The point is, nobody will be able to give a definite answer because there are so many properties and so many different markets in Boston.
