I will be occupying the main level of the home. 

@Kyle Grimm - I just transfer the questions over to a google sheet file and fill it out in there (and then submit as an attachment w/ their main file)   Then you have it forever and can just update it when you need to submit it again

I scoped the main line and found that a pipe in the basement has completely rotted away.

The home inspector thinks it’s an issue for fha.Secondly, there is exposed live wires in the main house attic and remodeled garage attic.The sellers realtor has been a bit difficult to work with.

I have a 4-unit property in Maine that I provide heat & hot water that are currently off of the oil fired boiler. 

The strategy would work  better if it were your primary residence, but it becomes more difficult if you're trying to convert a SFH to a true two-tenant duplex.1) You'd must likely be violating zoning (Unless area was zoned MF), so you'd have to hope the conversion flies under the radar.2) Utilities is the biggest hurdle, as a SFH only has one water, electric, and gas meter.

The main requirement is that any property purchased in an opportunity zone must be purchased through an Opportunity zone fund.

@Jared Smith I own 20 units and also mainly work with investors as an agent!

Cap rate and price-per-door are two of them.But your main concern is not finding deals in your local market, Denver. 

But FHA is the main law you need to worry about.
