If the numbers are right and you have a killer deal, consider a hard money lender/loan.

But lumber prices are keeping new construction down, which keeps inventory down, which keeps prices up. lumber is one component.. land prices and land use policies and entitlements are more of an impediment to new construction than lumber prices.. at least from my point of view as someone who has built over 250 new homes the last 7 years and has a 90 home subdivision going right now.. ya its a pain when lumber goes up.. but its not a deal killer and we are selling all our homes basically before completion.. so fingers crossed it keeps going that way.now this is also market specific.. 

Hustle + a unique skill, now that’s a killer combo.

If your DTI was at 50% before the HELOC, this can be a deal killer so run the numbers accordingly. 

The HOA fees are cash flow killers.  

Owning rentals seems to be an economy of scale and more doors means more tenants which means higher probability of stability in my overall portfolio (that’s my though process anyway)However, tenant quality and turnovers can be a cash flow killer and that’s where I’m stuck.

I think you'll find that most people who are getting killer deals aren't finding them through web sources like loopnet, trulia, zillow, etc.

It's an ROI killer. 

Taxes are such a killer in Buffalo Grove I would not be surprised if there is close to zero appreciation/rent growth over the next decade once rates start to tick up.

As long as the loan you have isn't an FHA loan, I don't believe it is a dealer killer.
