If you buy a high cash flow property in Cleveland, over 5-10 years you will most likely break even on the cash flow or just be treading water.

If you have a 6 bedroom in an area that does not have a university (students looking for shared space) or is in a family friendly place it may sit vacant longer between tenants.For Capex, try not to use a generic number - look at the roof, furnace, hot water tank, kitchen - when will each need to be done and what will it cost?

Its extremely important when running tighter margins like what you're talking about to focus on age of HVAC, water heater, appliances, roof, etc.

I assume it has sewer/septic, water and electric and they 2 tiny homes are plumbed/wired?

If the number are close[100k or less], do preemptive due diligence [water, sewer, stormwater, planning and zoning] if the property is considered for a new build development situation.

It blows quickbooks out of the water with ease of use and I can do the class tracking that the basic $20 a month quickbooks was lacking.There's a phone app also, I just added it to my phone, so I'm not sure how much I will use it yet other than for reference as opposed to opening the website for details. 

The hardship in my case stemmed from the fact the parcel size required a storm water management system that would cost the same to implement if I built 7 homes or 30.

I estimate high of what the bill would be and put it on their lease, I have not had any issues this way and if the water bill goes up, I will increase on the next lease. 

I do not have loads of cash at hand, I have a few connections which I could potentially pool some cash together with.

Given this is where my major operating expenses fell (beyond taxes and insurance), keeping this cost lower, by average, helps my cash flow.I invest in older neighborhoods, so the 2-4 unit properties, typically have single water meter, maybe single electric, and many have radiator heat with a single boiler.
