I just looked to how underwriting is done with mortgage qualifications.

The most common strategy is to use the existing equity to put into another downpayment and buy another property - this provides an effective use of leverage as you are expanding your portfolio.

I reached out to the realtor to see if they can provide a name but they are also trying to get a name as it seems the tenant had a verbal agreement with the previous owner so no existing lease document.

Because if it costs you $2K to $3K, it should give you ~4x in that in tax savings, or $8-$12K which is not happening).It's important to understand that a CSS doesn't create additional depreciation but rather accelerates existing depreciation.

I’m selling a home for $330K if I offer owner financing, I’d ask for $130K-$150K and then the remaining monthly amount until the mortgage is paid off.

This means you are doing it strictly for the cash flow.If it were me, I would go the ADU route, Rents could be comparable to the condo without the HOA dues (yes higher Cap-Ex but those are long term expenses), and with everything on one property, things are just easier to manage (one mortgage, one property tax bill, one insurance, etc.). 

There may still be other encumbrances (judgments, priority mortgages, taxes, or liens) that survive the sale.

I will be able to cash out my original down payment + 30k more if I wanted to but as im going through the process I was wondering in the future if I pursue investing full time how do you still get approved for mortgages?

I own a house in OH (no mortgage) with my relative.

I know this is because I have been focused on the DTC/SF traditional mortgage options or funding with buying an existing structure, but I can't see a clear path to financing a 2-fam new construction that's owner occupied (allowed by right per zoning).
