You will spend 10X on repairs and servicing of a poorly manufactured window so better to spend a little extra up front.I've recently had success using Harvey slimline windows on some rehabs.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

On a "small" loan amount like his, he found it more beneficial to pay the extra .25% to rate to get the 3 year PPP. reason: it added only $17 per month to his payment every month; a small price to pay to open the door for refi or sale 2 years sooner. 

I was thinking having extra saved would help as well.

I always need to be busy so the "extra layers" that asset has is interesting to me and the value I can create is amazing.I like to keep busy if you can't tell.

So I get good mental exercise here, or try to, while getting some added REI "fix" and if I can get challenged that's just extra credit, as is learning something new is icing on the cake. 

Ex (random numbers pulled out of thin air)$100k purchase $160k ARV$30k reno but $20k at cost$15k holding costsTotal Cost:$145k cost or $135k with contractorWith the contractor at cost, I have an extra $10k of margin where I don't lose money, but obviously not ideal for the contractor since they would make less.I think a good way to price it would be the equity would equal your profit if you did a fee construction at slightly below the projected ARV, and slightly below the projected hold time.

It makes sense to rent and save up that extra money to apply towards a future purchase. 

One of my current tenants in Denver lists the extra bedroom as an Airbnb arbitrage and I was totally okay with that, it's his residence and as long as rent is paid and he has the proper licensing/insurance then sure.
