I can't say I know much about land financing but if I was in your situation I would get in contact with some local or even national mortgage brokers.

For example let’s say in your market a water heater replacement costs $1k (my market is ~$1500 if using license plumber but our water heaters are different and more costly) and last an average of 12 years (our actual data going back almost 50 years places average lifespan just under that for gas water heaters).  

I am a local loan officer that works for a mortgage brokerage in Chandler also, let me know if you have any other questions. 

If you can get a local agent to pull a list of recent transactions, you should be able to estimate, based on the photos, what your target property will sell for post-renovation.The repair budget is the list of repairs (with estimated costs) required to make your target property look like the "ARV homes" you found above.

As far as what I do, I am a funding specialist and work closely with real estate investors to raise capital tax-free by using a specially designed holding account that grows your money between 5%-10% of interest and when it is time for you to pull the trigger on the next property purchase, you will enjoy a much lower lending rate of 3.5% - 4.5% on time for their next property.I've been doing this for 9 years and have worked closely with real estate investors for the last 4 and a half.About my future goals, I am interested in partnerships with other investors within the local area (Bay Area).

Do you want to invest locally?

I'd ask my local banks/CUs/ mortgage broker if they do portfolio type, asset-based loans.  

I'm local

I have brokers lining up some pre-approvals but wanted to see if anyone has had some local success with conventional financing or some type of rehab based loans. 

Since I will now be a local landlord of 4 doors I wanted to take over management myself - self manage to save money and have more control.I will use Zillow and FB marketplace to advertise vacancies.
