I recently completed a major renovation on my property financed through a Fannie Mae HomeStyle Renovation loan, and I'm now looking into options for removing Private Mortgage Insurance (PMI).

And for vast majority of persons delayed debt payments results in accruing debts, because they find they have less left to pay down than hoped.

Some of the questions I'm asking are as follows:- Age of roof and HVAC - Any major maintenance issues/fixes done recently

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.  

Since you and your wife have renovation skills, targeting properties that need minor improvements can maximize your return on investment while minimizing the time and cost associated with major renovations.

Or if you plan on staying in the property for a while, some people aim to just pay less than their current rent.In a real estate market where housing affordability is a major concern, house hacking actually stands out as an even more valid strategy than ever for buyers.

But I think the majority are not adapting to say the least. 

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

The vast majority of "regular" or traditional (Conv/Govt) mortgages are originated by specialty lenders and brokers and are sold in the secondary market to provide yield on bank balance sheets (think Chase or BoA) or to be securitized into MBS.

However, I would avoid neighborhoods where the vast majority of the homes are owner occupied and all of the homes are really well kept - you can do a quick search on county GIS or software and click on the homes to see if they are owned in personal names or LLCs.
