The worst part was both appraisers used comps from over a year ago, and in a hot market that makes a big difference, and I'm confident they were anchored on the purchase price  (both acquired ~15 months ago) even though we invested in upgrades. 

The free membership does not give you the most current listings and you would be unable to upgrade your listings. 

Hey Guys I have a creative deal I put together and the financing for it is going to have to be just as creative.I am buying two properties next door to each other and subdividing portions of the very large backyards to create a 3rd lot to sell for the profit (see pic.)Both home are in good condition and upgraded (minimal oppotunity to add value.)

What things should I upgrade in the house that will bring the rents and the home value up the most?

If you cannot access the property to get a good idea of what needs repairing/upgrading then it is hard to estimate a Rehab budget. 

And most of it is older stock built 30+ years ago needing upgrades. 

Thanks for the response, I am comfortable putting a decent down payment down but I still want a good amount of cash to wiggle with for any unexpected things / upgrades before going on the market. 

And don't forget that the redemption period would require the buyer to pay you for all upgrades +10%. 

Anything not projected to last a minimum of 5 years is replaced/upgraded.  

I've lived in the property for almost 4 years now and am looking to upgrade my primary residence for a little more room for the family and rent this one out.
