Contractors like what is being described are simply not going to pay double or triple because of financing. 

Looking to either partner ($$$) or simply find a trusted, consistent source of contractors in either city that can assist with my fix and hold needs.

Although I have guidelines when selecting a tenant, but because I am the one interviewing and usually showing the property, I have the flexibility to cut corners when my gut says so.  

Even if market comes down, someone else with cash under the mattress will come out to place a floor on the downward movement. you cannot simply create more housing supply because commodity prices are stuck at elevated levels, and new builds will remain higher cost than existing inventory. 

Just a little rate cut and you get a boat load of unseasoned loan officers cutting their comp to win over the deal. 

Or, is it simply because wholesalers are illegal brokers who are lower IQ than most Realtors?

You can’t just take one name off because the other asks—both need to agree in writing.Don’t cut corners on documentation.

The outcomes of these deals have gone far beyond simply building a portfolio of 250+ units.

Costs in many locations don't pencil and you need equity that will be patient because significant rate cuts are necessary to recycle out equity on new construction multi-family deals at this time.

Simply negotiate that with the tenant and include the language in the amendment that tenant is paying in $xxx additional SD at time of signing the lease amendment and put the total amount of the new SD balance held by you so it is clear to all parties how much the tenant has paid in.
