I'm going through the FHA process because this is a loan assumption and able to get a very favorable rate.I'm wondering if anyone has gone through this process being a pure real estate investor (no W2 or other income) and how they would handle this situation.

Given our financial constraints at the time, we couldn't afford such a high sum for limited coverage.I'm told that the lapse in coverage for the few months between being dropped by our previous insurer and attempting to get a landlord/investment property policy will make if VERY difficult to get a policy.I'm not sure that my agent really has much experience in insuring investment properties/rental properties.I reached out to Arcana (now MSI, and they forwarded my a list of agents/reps that could work with me.My question is: Are there any other places I should be looking to obtain coverage?

Though I don't think NOI in residential has any practical use in valuations or towards other financial instrument applications, it definitely is helpful to analyze synergies forecast in OPEX when you get multiple properties.

The listing agent should have all the info available to potential investors that they'll need to make an informed offer however including rent roll, financials, photos, proforma, sometimes current leases redacted and sometimes (more rarely) even a recent inspection or pre-inspection, etc. 

=> I would get a local lawyer spun up on the situation when the investor is ready to go.

U can keep trying but as stated your best bet is a financial ( cash partner) and then you have to talk them into why they should give up a bunch of the deal to you.

I am in school for Personal Financial Planning and want to get my certificate or real estate license while in school.
