No, he's not an architect, he drew all designs, floor plan, site plan, etc, and we had a structural engineer design his part, and paid an architect to sign off on them.  

The rental should be paid off in about 3 years.

I also kept my first home and it is paid off now and worth approximately $150k, with current renters. 

That will not get you to 100k as at best you could go DSCR and get 80% (if numbers even work).Regarding property not complete, if you have paid cash to date, your best bet would be to get a hard money loan for $100k to complete the renovations and pay off some debt and then refinance once its completed.

They discussed pre-foreclosure, auction, and REO properties and points to consider on each. 

We paid this out of pocket. 

At $10/hr thats $1600/mo so even if you spend $5k - get one deal its paid for itself.

Not sure on the building size or whether it has a flat roof, but I paid over $80K to get a 10k sq ft flat roof done back in 2021, with quotes as hight as $120K.Hope this helps, good luck!

We paid cash and have no mortgage. 

I just had a client close his first refinance loan and he only paid $1645 in UW fee.
