from living in the basement while renting out the upstairs just to “save save save”  to combining property with my next door neighbor in order to build high end townhouses.

I would not get involved in properties this old without making a major effort to become aware of their typical strengths and limitations versus more modern properties.

I have started fixing up minor things and painting interior to make everything look more modern.

I use a combination of a few different applications.

I will bite...if you can go conventional loan, the max dti will cap at 50%...off 140k combined annual income, roughly 2692.30/week or 10,769.23/month...using 10,769.23 monthly, I would guess the sum of all your debts cannot exceed 5300/monthly (and some change)...if you already are at 3100, I would guess you have 1900 available monthly for debt service on your house...the lender will use the lower borrow's middle score.  

If you all would be so kind, I need some advice on a property we like.The house detailsMarket: Boston West / Worcester Area, great schools, close to quaint downtown, 15% rentals in town, 57% with college degree, AGI of $90k, population growth of 3.2% in last 7 years, unemployment rate of 4%.Property: Large old farmhouse that has been split into 2 two-bedroom units and those units have been modernized.

But, even in theseor “C” neighborhoods, I’m finding the prices on these properties combined with the property tax are more suitable for people who just want to buy a home and not invest.

We actually do a combination like @Kevin Sobilo stated. 

If your objective is cash flow, I would strongly encourage you to look at markets that not only cash flow well but have a good combination of cash flow and economic/demographic trends.
