@Leticia Montoya usually you'd have a vendor for each major component of the rehab so one for the foundation, one for  HVAC, one for roof, and one GC to handle most other things, of course this varies given what a particular property needs. 

The amount per month can vary a lot -- are you trying to seriously build up enough reserves to cover all the major components that will need to be replaced over the next 20 years or so?

Just tell people there will be a credit check ran, but it is only one component you consider along with income and criminal history. 

Does anyone know if theres mortgage, transfer, tax, or any other data that might align with these types of properties more accurately?

I would agree, especially now that many of the new units have a myriad of computer controlled components.

I wouldn't pay for any tune-up as it seems as though individual components will fail over time which are easily diagnosed. 

So you may align better with some passive strategies.

If you own your home, it is likely that will be a key component.  

Wholesaling in our industry is more aligned with unlicensed brokering of a property.

But there was an appreciation component, due to the reasons listed above.
