Should I add one or two more? 

Maybe they will want to buy a house one day and decide to pay me off.

One thing is certain, we'll find out together in 2025!

And not have to go with one of the free firms, who invest your exchange proceeds in lieu of collecting exchange fees.

design one for yourself. think about your market. like in columbus we have infill lots at 30x120 and so we developed and designed a house for ourselves. we build the same house and continue to Make modifications. it's the only new build we offer to build for clients. that's just my opinion. architects we didn't even use we looked at national builder Floorplans and decided. our typical lot is 3000-4000 square feet that we build on 

haven't been able to get one yet. 

However, our current hard money lender only funds one loan at a time, limiting our ability to take on multiple deals simultaneously. 

One key piece of advice is to make sure to build strong team around you.

The ones with no seasoning periods will make you pay dearly either with the rate or with loan costs.In the scenario you mentions above, if you bought a house for 30k (you didn't mention doing any work, but I assume since you mentioned BRRRR there is a rehab), you do the work and get a renter in there with a lease and then after the seasoning period, you now can refinance based off the new value of 165k of which you should get 75%.But why 15 yr mortgage, why not 30 yr to make the payment smaller?  

That's a mine field no one on here is qualified to answer. ;) But your rental is doing well.
