If those extra payments are going to move the numbers below your minimum investment criteria, then no, it is a poor way of funding a down payment.

Unless you can charge a premium on rent for having hardwoods that is enough to offset the extra cost of install, perhaps consider vinyl or laminate? 

I am self-employed, and even though I have a sparkly credit rating and plenty of savings to make the cut, meeting the underwriters' requests turned into an extra part-time job for several weeks.

(which I don't think she is) It would also add a ton of extra closing costs that wouldn't have been involved when whole-selling.

You're not required to do anything extra.  

Remember with commercial units / loans there will be a lot of extra fees involved: two closings, maybe two appraisals ($1600 for a 5 unit that I did recently), permits, inspections etc.  

It's really a math equation here Deb, but we're missing a piece of the info, and that is what you can reasonably expect to gain in rent from having the extra bedroom.

I'm not sure what their split is.Starting out you'll have to be extra cautious since you may not know how this contractor performs.

So why does the the Agent need my credit report… An eviction report is all that is needed and that is a very inexpensive report to obtain.People can have bad credit and still pay their rent every month.People can have past criminal records and still pay their rent every month.People with a prior eviction could still pay their rent every month.Plus, an eviction report is the only report that’s specific to the rental industry.To me, requesting a Credit Report to Lease a home is just a scam to make extra money for the Agent.
