Hey Rich,
A few thoughts for you:
When looking at land to develop- I'm focused on 2 primary things (I go into more detail below).
1. What is the zoning - can I build what I think there is demand for in the market (retail/industrial/apartments etc).
2. What is the demand? How deep is the demand? Can I secure leasing or presales prior to removing conditions?
How I do this- I'll invest $5k+/- for an architect get me renderings and plans. I'll have a commercial broker (for commercial) go the market and pre-lease.
If it's retail- I like to have an anchor secured with a lease (subject to DP/BP) prior to going unconditional.
Next- you're asking about working with a GC and getting bids.
Without plans, you will have a hard time getting real numbers.
They should be able to give you costs, based on price per sq.ft on building, base building, soft costs, site serving, site work, grading/filling (assume you have geotech), permits etc.
If this is your first deal- find someone locally who has done what you're tying to accomplish and ask who to stay away from and who to work with.
From experience- there are many architects and GC's in the world but not all will be the right one for your project. Relationships are key in this business. I've learned the hard way- hopefully you can avoid that.
Below is a post I wrote a while back and might be helpful.
1st. I buy the land outright- with cash. As I syndicate, this means, I raise the money from my investors and close on the land. You suggested you're closing with a private lender. Nothing wrong with this- BUT, private lenders typically don't do a lot of DD.
THey assume you've done your homework and if you mess up- they take back the property. Are you personally guaranteeing the loan?
2nd. I De-risk my Deal
- I don't buy on spec. So, I've either got pre-sales (in the case of my industrial condos - where during due diligence and prior to removing conditions, we pre-sold 70%).
- Or, I will pre-lease and find my anchor tenant(s). So my downside is breakeven (provided I've done my homework on construction costs).
I generally have my drawings near completion to go in for a DP during DD.
I will have a very good # from my GC on the development at this time (we won't go to tender until we remove conditions and have an approved DP).
During this, I'm speaking with my bank. How much debt can I get? When?
In a development- you're running many process simultaneous - so it's hard to say do this first and this second.
My main focuses:
1. what is the demand for my site (and how much revenue can I generate). I will adjust my site plan and renderings numerous times to accommodate the demand for the market
2. how long will it take? Timing is critical (DP, BP, leasing, construction).
2(b). how much will it cost? Does the deal make sense? Can I achieve the rents or sales required to justify the development (I like 100% ROE, or 35%+ leveraged returns. Development is risky, and if I don't have sufficient buffers and incentives, then the deal is too skinny)
3. What are the risks? what can wipe me out?
4. How much debt will the bank give me and when? What thresholds are required. My bank wants about 65% pre-leasing or sales to advance funds.
5. Once I have this, I raise my equity and then extra. One of the biggest mistakes I've made in the past is raising too little money and then having to go back to investors for more. This is something you'd rather not have to deal with. The project paid out very well still- but, during construction, was stressful for me.
Side Note: You may want to have a commercial mortgage broker with experience in construction financing assist to. They can help you through some of the steps above- what I've given you is the high level on how I look at and do my deals.
Commercial lenders will also point out some of the pitfalls in advance
Hope this helps
