I would suggest a minimum of 9 months of debt service. 1 month is playing with fire. 

Sometimes you need to play with fire to really learn I guess 🤦🏼‍♂️

Not too shabby since it was something he could afford 25% down and is making a small profit each month.As far as resale, we buy and hold so that number doesn't come into play for us.

This neighbor unknown to my mother, had built a chicken coop, play area, parks his vehicles on the lot, installed a garden and to top it off - built a wire fence around my Mom's lot!  

I'm not a lender, so I'll speak to this as a fellow real estate investor.Looking at primary residences you're best low-money-down play would be a 3.5% down FHA loan, or a 3 or 5% down Convetional loan (unless of course you have access to the 0% down VA loan).
