Need to account for CapEx. 15% combined for Repairs and CapEx is usually good.Will you be responsible for any utilities (like water/sewer) or lawn care?

Can you convert the heating to electric combined with going solar?

If there is a shared meter situation, I try to increase the rent to cover the utility costs and then combine the utility with the rent.

I think I’ll have a combination of the two, working and some parent support.

All that crap is baked into your rate. 

This is more common in older TH than newer ones but sometimes developers go the cheap route and make and start combining roofs.

For an older house, I would probably use a total for 12-15% for combined Maint/Cap Ex. 

If there were some structure in place where the PM was able to take some percentage of the prophet combined with some measure of how the overall asset was being maintained, I would be more interested.Something like, the longer a tenant stays and the better the property is maintained the more the PM takes.My experience is more of a heads the PM wins, tails I lose. 

This is ideal to be combined with item 1 and/or 2.We have used each of these to some degree (we never purchased as low as 70& ARV). 

Sellers are culling the crap out of their portfolio and trying to sell junk to unseasoned 1031 buyers who do not know how to properly evaluate what they are buying.There are still plenty of deals out there but lots of buyers going for them so those properties last less than a week and under contract typically.
