Transitioning area from C/B to A in five year span.

I placed an ad to gauge and received about 20 inquiries in a two day time span.

I understand an AC or a roof has a life span and they will eventually need to be replaced but lets assume after 15 years of holding the property, nothing broke or wore out.What are peoples experiences with this?

In the span of a year nothing changed for me and if anything it got better but the bank decided they wouldn't renew and told me they would foreclose if I couldn't refi somewhere else.

There are a lot of off-market deal opportunities which may produce better results than using zillow, realtor, MLS, etc.Be aware that with an FHA loan you will be paying mortgage insurance throughout the entire span of the loan, unlike other loans where the mortgage insurance stops after a certain percentage of the principal has been paid off.Prepare yourself with some financial homework on the properties you are looking at and how much ROI you are going to get and be ready to pull the trigger.Also be very aware that Massachusetts is a tenant friendly state with almost seemingly unfair laws 'against' landlords so it is best to be aware of the Massachusetts Tenant and Landlord Laws and have a very good tenant screening process. 

You really need a span of 8-10 years to normalize a yearly percentage.

And if you're flipping, it might end up that you have large spans of time between deals where you don't have money coming in to live off of.

I like to also look at how rents and ARV change over time to determine the long term historical average/trend ... note I said "long term", not what prices or rents did last year or the year before, but over decades spanning multiple RE cycles.

Asset classes cycle at various times typically 7 to 10 year spans.

Aliquippa zip code spans a very large area.
