As great as PropertyRadar is and it is pretty darn accurate, it's not intended to replace due diligence of good ol' title research. 

I would say it depends on just how "move-in ready" you are expecting.If someone is sitting on a property that is in relatively good repair overall, with the exception of some paint, flooring, and minor kitchen updates (countertop replacement/cabinet refinishing) for example, as a result of inheritance or a property that may be more of an afterthought for whatever reason, then perhaps through direct mail you may uncover a handful of decent leads/deals whose owners haven't necessarily yet put the wheels in motion to get rid of a property that they may consider selling once they are given a slight nudge.

Instead, replace it with short-term goals that are more "realistic" within the realm of investing such as completing your first flip by June 2015, or owning 3 rental units by Dec 2016.  

So with this being my first experience in having to replace an old boiler, I was surprised to find that this is standard practice. 

So yes, the place is small and the area isn't that great, but it's increased in value almost $250K over the past four years so I'm ready to sell and walk away.Elizabeth Colegrove , I guess I'm "risk averse", and despite a > 800 FICA credit score, I'm not sure how easily I'd get a reasonable mortgage since I'm hoping to use the rental income to replace my W2 income within  couple of years.My basic goal is to purchase enough units (1-2) within two years to cover my day to day expenses until I start drawing from my retirement accounts and portfolio in my mid 60s (20 years from now.)

It is a duplex with nice tenants and a lot of important things replaced within the past few years so it won't be needing a lot of repairs.

How much estimated to replace this siding on 3000sq ft home?

The numbers are as follows:Sales price: $115,000Insurance: $452/yearTaxes: $1252/yearUtilities (gas, electric, water, sewer, trash) (Unfortunately two of the units share a meter, so these are paid by the landlord for simplicity sake): $300/monthRents: $1645/monthThe roof has been replaced within the last year.  

Machines will need replacing causing a lot of capex outlay eating profits.

That said, if you own a property long enough, you will need to replace a roof and could need tuckpointing and probably a sewer line if it's still the original 90+ year old cast iron.
