Is there a way to passively track mortgage rates on 5+ residential apartment buildings?   

They are a great person & I wish them the best of luck for future work.However, I'm somehow unable to justify the $25k+ I am expected to pay to them as commission on each $1M invested.If I am researching the market myself, creating comps myself, reviewing each disclosure myself, working with the mortgage lender myself, finding problems in the homes myself -  what is the value add that the agent is bringing to the table that I can't execute myself?

Loan Officer, Brave Mortgage called me and we started a refinance option to be able to hold the property and get out of the balloon payment.

I'd recommend looking at costs. your build cost is going to be well over other homes because of the fixed costs like slab, Hvac, roof, etc. check the market drivers and weight the benefits of short term versus long term. long term is no furniture and help pays mortgage but at this size it doesn't really cover everything. we didn't find a lot of economies of scale in single family detached. can you build more than one unit?

Some need to sell and will let you take over the mortgage while leaving a bit of equity.

If I secure renters and show a lease agreement and deposit can I get into lower interest rate mortgage?

Investing in a mortgage fund should not have tax implications for your Roth IRA since the investment is passive. 

The bank and mortgage company we are using is giving us a hard time about us co-signing due to my separation and new job due to only having been separated a couple weeks now.

You would use a mortgage servicing company just like a typical mortgage.

If they can get insurance rates and mortgage rates to come down a little, we would have a light correction imo for SFH.
