At the end of the day; you need more money to do something like this.MAX LTV on new builds is 80% LTC, Meaning if the build is $550,000 and Land is XAdd ($550,000 + x ) * .8 = LOAN AMOUNTYou would need to come in with MINIMUM 20% of the cost in addition to closing costs and reserves, $80,000 is not going to cut it for this project.

Maybe you mean closing costs?

Now, with the ADU rules, developers are buying anything close with some extra space so there may only be scraps left that wouldn't pass FHA or would price you out.

Just because the property can close in an LLC with a DSCR loan, does not mean the loan is made to an entity.

Build a solid foundation before taking a step up - each and every step of the way.There’s a way to scale recklessly and there is a way to scale safely.When OPM is involved safe is way better than reckless.Despite a life long career in RE, I scaled as followsBought a few duplexes for my own accountBought a fourplex for my own accountBought 12 units as a JV with some friendsSyndicated 43 unitsSyndicated 30 unitsBought another 12 units as a JVSyndicated 281 unitsThis was over a 3 or 4 year period.and so forth - now I am GP in close to 1000 units with $125M AUM.Even with all that, my sweet spot is 30 to 50 unit properties - they work best for my partners and I and more importantly our investors. 

We also have many unique buyer incentives where an investor can get up to a 10% price reduction to come into immediate equity, or get that 10% as a cash back at closing to reduce your down payment and increase your ROI, or buy rates down into the low 4s on 30yr loans to maximize cash flow.

What they will offer you is an appliance package, or closing cost help, or a low fixed rate loan. 

In terms of other factors, I'm not sure there's a lot because I did have some people express interest in filling out an application before, and I actually got really close with one potential tenant, but it was because of the alcohol policy that he ultimately decided to back out.

3) Your $250k with 30% down => about $750k (you also need funds for closing costs, taxes, etc.)

But you have closing costs for Refi, and sale, but in sale you get all your equity back out.
